[Windows] WebView doesn't display url when inside a VerticalStackLayout

Description

I recently decided to change the StackLayout to VerticalStackLayout.
If I place a WebView control within a VerticalStackLayout. the web page at Source is not displayed. If I replace the VerticalStackLayout with StackLayout, the web page is displayed.
Works fine on Android 12.1 - API 32.

WebViewTest.zip

Steps to Reproduce

1. Compile and run attached project as a Windows app on Windows 11. The project contains 2 pages. They are identical except one uses StackLayout and the other VerticalStackLayout.
2. Select "Display a Web page using StackLayout". This page will work as expected
3. Select "Display a Web page using VerticalStackLayout". This page will not work as expected

No response

Start with the attached WebViewTest.zip and run its two pages as a Windows app on Windows 11, comparing the StackLayout and VerticalStackLayout cases. Trace the Windows WebView and layout behavior, then verify that the page from Source displays inside VerticalStackLayout without regressing the working StackLayout case.
