NVDA announces most of the WPF dialog contents on opening "Options" dialog when they obtain focus

[jeremymeng]

Steps to reproduce:

1. Open Visual Studio 2017 (a free community edition is available at https://www.visualstudio.com/downloads/)
2. Invoke Tools | Options menu item
3. Type "Live Unit Testing" in the search text box
4. Click on the "General" node
5. Type TAB key

Expected behavior:

NVDA should only announce the checkbox that has focus.

In this case General grouping | Pause Live Unit Testing during build and debug check box not checked

Actual behavior:

NVDA announces most of the controls on the right pane. Below is what is showing in the Speech Viewer:

Note that the Visual Studio Option dialog hosts both Win32 and WPF option pages
on the right pane. NVDA has this behavior for other WPF option panes as well.

Another example is Text Editor | C# | Advanced option pane. NVDA doesn't
announce the whole contents of an option page when it is implemented using Win32
controls. Most of the Visual Studio Option dialog panes are in Win32.

Hello,

No, I don't think so.

Still occurs with latest alpha.

Cheers,
