Significantly speed up heading quick navigation in Microsoft Edge by walking heading Text elements rather than looking at all paragraphs #7343
Summary of the issue:
Currently navigating by heading in Microsoft Edge is extremely slow on large pages.
The current way this is implemented is that NVDA moves through the document by paragraph and checks the text attributes to see if this paragraph is a heading.
Description of how this pull request fixes the issue:
As of the Windows Anniversary update, Edge started exposing an real UIA element for each heading. It can be identified with a controlType of text, and a level between 1 and 6.
Change log entry:
That's cutting edge code. (Derek hides).…

I know this sounds like the edge case of edge cases, but I've seen these in the wild. — You are receiving this because you are subscribed to this thread.

what about this invalid, but still seen in the wild code? Will this PR break heading nav to these?
I see this at least once a month, and it is incorrect, but it is nice to be able to move by heading with them still.
