Same issue here after upgrading to WinUI2.6.
Can't interact with the webpage with the mouse...
Using Tab to focus on Webview and then PAGEUP & PAGEDOWN key to scroll.
And again clicking on webview, it loses focus as if there's some transparent control above webview.

@ranjeshj and @codendone FYI

Currently blocking upgrade of React Native for Windows to 2.6 - can we get this tagged as RNW too?

we have the same issue here, but when I open it inside a new AppWindow it seems to work

@RosarioPulella did you notice issues with the XAML Editor WebView when you updated our Sample App?

In CommunityToolkit/WindowsCommunityToolkit#4092 (comment) @XAML-Knight mentions that the editor does not respond to mouse or keyboard input. Also locally I can see the rendered xaml in the editor but I can't seem to interact with it.
