MS Word: Collapsed state not reported for headings in outline view

[CyrilleB79]

Steps to reproduce:

• Create a Word document with headings of different levels and body text in between.
• Change the view to Outline view
• Navigate in the document (outline view) and collapse or expand some headings with alt+shift+pavnumPlus or alt+shift+pavnumMinus. Note that the behaviour seems a bit different from what happens in other view types, that is, collapsing or expanding a heading may modify the collapsed state of other headings.
• Navigate vertically with up/downArrow

Actual behavior:

As per #17499, collapsed headings should be reported.

Expected behavior:

The collapsed state is not reported in Outline view (no matter if you use UIA or object model).

@SaschaCowley could you give more details why you have added blocked/needs-external-fix label? Have you or anyone else investigated? If yes could you write here the result of these investigations?

In discussion with @michaelDCurran we believe that this information is most likely not exposed. Have you tried with Narrator?

[CyrilleB79]

I am testing with:

• Microsoft® Word 2016 MSO (Version 2412 Build 16.0.18324.20092) 32 bits
• Windows 10 22H2 (AMD64) build 19045.5371

With Narrator in this environment, on Word, headings collapsed state is not reported in Outline view, but neither in page view. I.e. Narrator does not report the information reported by NVDA last alpha (after #17499).

According to #17499 (comment) and #17499 (comment), it's probably because I am running Windows 10, not 11.

Could anybody running last Word 365 and Windows 11 test in page view and in Outline view? (@michaelDCurran, @codeofdusk, ...)?

And if the issue is confirmed, report it to Microsoft?

@CyrilleB79 So Win10 Narrator doesn't read it but NVDA does? This is because Narrator uses UIA which doesn't support remote ops. I wouldn't expect a fix for this on 10 Narrator, sorry.
