When resolving the issue

Take care to test with UIA on / off, browse mode on / off. Thanks!

@mltony I can see that you have just made a release. Any chance to also fix this? I have just encountered the issue again in PowerPoint.

You should probably check if the focus belongs to a tree interceptor (and if it is active) to decide if you need to take the object itself or its root object. You can see such constructions in globalCommands.py.

@CyrilleB79,
So the first two exceptions are manifestations of this problem in NVDA:
nvaccess/nvda#16172
I never had time to look deeper into this one as I don't use Word much. Moreover it seems that switching to UIA mode in word can be used as a workaround. But yeah, it doesn't make any sense that you can't collapse a textInfo in MS Word.
I think I just fixed the third exception and pushed 1 commit in master branch. Could you check if the problem goes away?

[CyrilleB79]

Yes, this seems OK now in PowerPoint with this new commit. Thanks.
