The only other mention of this I could find, was by @JulienCochuyt in #10838 (comment), back in 2020; and someone talking about it on the wx-py mailing list, which got no response in five years.

Steps to reproduce:

Run any application which uses a wx.html2.WebView.
I will provide a sample shortly.

Actual behavior:

When attempting to focus on and interact with the HTML document,, its content is not spoken or able to be navigated.
The content is definitely there, as NVDA+R can confirm, but normal navigation will never find it.
If you force the focus (as described by @JulienCochuyt, or by mouse as I will show with an example app), it can be made to work. But that method is highly un-ideal.

Expected behavior:

Preferably, NVDA should switch into browse mode automatically, or should at least be able to manually (although most users won't know to do so).

Other questions

Does the issue still occur after restarting your computer?

Yes

Have you tried any other versions of NVDA? If so, please report their behaviors.

This has been going on since at least 2019.3, and probably since wx.html2 became available.

If NVDA add-ons are disabled, is your problem still occurring?

Not relevant, but yes.

Does the issue still occur after you run the COM Registration Fixing Tool in NVDA's tools menu?

Not relevant, but yes.
