[Bug] WPF null BoundingRectangle property

What happened?

We have a WPF application that contains a WebView2 control hosting web content. When our automation team runs the Accessibility Insights tool against our app the WPF View hosting the WebView2 control displays 6 errors stating "An on-screen element must not have a null BoundingRectangle property". When I looked at the Visual Tree I noticed the errors were coming from within the WebView2 control itself.

So to test the problem in isolation I downloaded the Main branch of the WebView2 Samples and loaded up the WPF sample. When I run the Accessibility Insights tool against the sample app I receive the same 6 null BoundingRectangle property errors.

I have included the Accessibility Insights test results.
