NVDA gets stuck on line in Windows Mail if you open an NVDA dialog

[chojiro]

Steps to reproduce:

1. Find a long email using Windows Mail
2. Go down to around line 60
3. Press a command to open a dialog in NVDA, EG (NVDA+Ctrl+S ) for the synthesizer dialog,
4. Press escape to close the synthesizer dialog
5. Try arrowing around the email.

Actual behavior:

NVDA seemingly gets stuck at this point. Closing the message fixes this, restarting NVDA does not.

Expected behavior:

NVDA should continue letting you arrow up and down as normal. Additionally, when this behavior occurs, you can't use NVDA+space to toggle browse mode.

If you require an example eml file, I can provide one.

cc @michaelDCurran @feerrenrut Given that this reportedly does not occur in 2021.2 it would be nice to triage this issue before 2021.3 is released.

[feerrenrut]

I can't reproduce this from the instructions given on Windows 10.

[seanbudd]

I can reproduce this with 2021.3beta2 and Windows 11. I don't know the technical NVDA term here, but it visually appears as if the focus/browsing mode has changed when returning focus to the mail window.

[seanbudd]

I could also reproduce this with 2021.2 and Windows 11

[michaelDCurran]

I can also reproduce this. In fact, it does not have to be an NVDA dialog, but simply focusing anything else in the OS and coming back to Mail is enough. However, you need to be scrolled enough down the email so that the message headers disappear.

[feerrenrut]

Because this only affect those on Windows 11 and 2021.3 is close to release, we will target 2022.1 for a fix. There is a work around for those who have already updated to Windows 11: Close and reopen the email message by pressing escape.
