Initial support for Windows 10 anniversary versions of both Microsoft Edge and Windows 10 Mail.

#6271

Merged

Re-implement rich text support for Edge, compatible with RS1.

Add missing import

EdgeTextInfo: ensure getTextWithFields never returns controlFields for the root element.

Edge: report landmarks

EdgeTextInfo.getTextWithFields: chop redundant fields and text off the end that are incorrectly placed there by Edge (E.g. expanding to line before a list, table etc includes the list or table).

Edge now correctly sets focus on its root container and or document, thus we no longer need to blindly allow all UIA focus events on the root container.

Edge: fall back to name, value or description for embedded controls where appropriate.

UIATextInfo: implement support for more formatting (color, alignment, linked, bold, italic, underline, strike through, super/subScript).

Edge: Ensure previous heading quicknav does not skip over same-level headings.

UIATextInfo._getControlFieldForObject: ensure controlFields stay unique per object by adding UIA's runtime ID to the controlField.

Edge: Remove any whitespace directly after the end of an element as it is not needed and stops us from correctly chopping the extra elements accideintally included by Edge at the end of lines.

Edge: _getTextWithFields_balanced and _getTextWithFields_unbalanced don't need to collect information about their root element at all. In deed, _getTextWithFields_unbalanced shuold *not* recurse after its root element. Stops an infinit loop when dealing with aria-hidden text.

Edge: focusing a selectable list item (E.g. an auto suggestion) should switch to focus mode.

Edge: Ensure a control's name is announced, (but not twice) with moving with quicknav.

UIA NVDAObject: Make use of UIA fullDescription in the description property if available.

UIA NVDAObject's description property: only use fullDescription if it is not equal to name.

Edge: use localizedLandmarkType instead of localizedControlType when fetching landmarks.

Edge: expose the clickable state on text, groupings, sections and graphics, if they can be invoked.

Edge: _getTextWithFields_balanced: specifically handle detection of an embedded child (checkbox etc) at the beginning. This stops skipping out of the document when a control is inside a label, and standardizes this check with similar checks in other parts of the code.

Edge: make use of some existing base code when walking formatted text.

Edge: integrate the main code from _getTextWithFields_balanced in to _getTextWithFields_unbalanced which allows for a substantial removal of duplicate code.

Edge heading quicknav: re-implement using move by paragraph and getAttributeValue rather than findAttribute.

speech.getFormatFieldSpeech: If the user has chosen to report headings, and the unit is either line or paragraph or the reason is focus, always announce headings in intial formatting even if the heading level has not changed.

Edge browseMode: allow aria-label / aria-labelledby to override content in certain situations.

Edge: detect iframes and give them an appropriate role.

Edge: work around MS Edge bug where expanding to character on an a control such as as a checkbox does not include the control in its children or enclosing element. Also ensure these controls are focused with using quicknav / arrowing.

Edge browseMode: report number of items in lists such as in other browsers.

Edge browseMode: rough implementation of quicknav/listing landmarks.

Edge: provide _startOfNode and _endOfNode attributes on controlFields to help braille presentation.

EdgeTextInfo: override move and expand to skip over element start positions that have no character representation.

Edge: expose overridden content always via value, with a single space text field as content. Change braille to handle value if always ReportValue exists in the controlField. Ensures that routing works with content overridden via aria-label etc.

Edge: only expose heading levels in initial formatFields. Braille: support heading level in formatFields.

EdgeTextInfo.expand: don't try fixing up expanding of line and paragraph. Just causes issues. EdgeTextInfo._normalizeUIARange: ensure not to jump over embedded controls.

UIATextInfo: move spelling detection into getFormatfieldAtRange.

UIATextInfo: abstract a lot of Edge code, replacing the old UIATextInfo textWithFields code with what has been learned from Edge.

Abstract more Edge code into the base UIA support, including a base UIA browseMode implementation, making it easier to offer Browse Mode for Win 10 Mail etc in future.

UIA: don't raise an exception on mixed text attribute values if there are no more UIA units to try.

UIA: Initial support for Win10 Mail browseMode (UIA MS Word support). For now force browseMode with NVDA+space for read-only documents.

Edge: don't expose clickables if they are descendants of clickables.

Add an appModule for Win10 Mail (hxmail) and provide browseMode automatically for read-only emails.

Add missing imports

EdgeTextInfo.expand: only do special expanding for embedded children if the unit is word or character. Otherwise expanding to line from an embedded control won't cover the entire line.

UIABrowseMode: don't use ReviewCursorManager as Mail does not need it. Instead only use ReviewCursorManager specifically for Edge.

Report position in a document when pressing tab or shift+tab.

UIAUtils: add more doc strings.

Win10 Mail: stop reporting 'edit' for each line of documents.

Improve performance of navigating in Edge browse Mode by about 20%.

Remove the need for overriding focusableNVDAObjectAtStart on the EdgeHTMLTreeInterceptorTextInfo, and therefore the need for EdgeHTMLTreeIntercepterTextInfo, by allowing UIA BrowseMode's iterNodesByType and UIATextInfo's NVDAObjectAtStart to share logic that finds the deepest UIAElement at the start of a text range.

UIATextInfo._getTextWithFieldsForUIARange: remove redundant check.

Review actions for #6271

Edge: Report editable combo boxes as editable and allow them to be found with e and shift+e in quicknav. (E.g. Google search field)

Untested idea as to how to handle content overriding in controlFields.

Edge: Where content is replaced via aria-label etc, ensure that content only takes up one character stop. Also ensure that braille shows the entire line for certain complex textWithFields runs.

Braille: no longer support alwaysReportValue as it is not needed.

Address comments in #6271

EdgeTextInfo.expand: remove code that tries to exclude content from the next line when expanding to line/paragraph. Other code already handled 90% of usecases. This code fixed one and introduced one. For now minimal is better.

Edge NVDAObject: catch a case where a text range could be NULL.

UIATextInfo._getTextWithFieldsForUIARange: handle where IUIAutomationTextRange::getEnclosingElement is not implemented (File Explorer search, Win 7 start menu search)

NVDAObjects.UIA: allow module load where UIA is unavailable (E.g. XP).

Handle broken WPF UIA text pattern (E.g. 1Password):
