Fix error fetching details (PR #13456)
Summary:
- Gecko applications (Firefox / thunderbird / instantbird) were occasionally raising a COM error "No such interface supported" when aria-details relation is fetched.
- This exception should be handled as per getIA2RelationFirstTarget.
Additionally:
- getIA2RelationFirstTarget failed to convert IUnknown to NVDAObject.IAccessible. This was missed due to failure with typing system, ctypes.POINTER(IUnknown) is not recognized and becomes Any.
- Unnecessary Firefox error logging on a missing detailsSummary.
This change:
- Prevent ComError escaping when checking for aria-details by using getIA2RelationFirstTarget directly.
- Ensure that IUnkown is converted to an IAccessible in getIA2RelationFirstTarget
- Remove unnecessary Firefox error log on missing detailsSummary.
Fixes #13433
Fixes #13430
