Resizing WPF Window causes WebView2CompositionControl content to flicker and disappear

Description

Reproducible with out of the box Blazor Hybrid WPF app (haven't tested same scenario in MAUI).

https://learn.microsoft.com/en-us/aspnet/core/blazor/hybrid/tutorials/wpf

With Microsoft.AspNetCore.Components.WebView.Wpf version 10.0.10, resizing the window produces tons of flickering of the webview content alternating between rendered and a blank content area, or even completely rendering blank until resizing is stopped.

This can result in, when the resizing is stopped, the entire content of the webview being blank if user just happens to stop resizing at the right time. Even if the content is there when resizing is stopped, the overall experience looks terrible.

Version 9.0.120 does not have this problem. Something is wrong with the WebView2CompositionControl in the new version.

Relevant log output

Start with the out-of-the-box Blazor Hybrid WPF reproduction described in the issue, using Microsoft.AspNetCore.Components.WebView.Wpf 10.0.10, and inspect WebView2CompositionControl while resizing on Windows. Compare its behavior with version 9.0.120; done means resizing no longer causes flickering, blank content, or content disappearing after the resize stops.
