Don't braille or speak duplicate name / content / description (PR #12888)
When a link had a title attribute that matches the content, braille (and speech) was duplicated.
Tests have been added for speech, to show current behavior (duplicated name/content/description)
The duplicate speech/braille is fixed:
- In focus mode, ensuring that description is not reported if it matches name
- In browse mode, when filling the virtual buffer identifying when description matches the node contents and adding an attribute.
