Describe the bug
Scrolling with the mouse wheel when the pointer is over a WebView2 does not scroll the XAML panel of that WebView2. This worked in WebView(1) in UWP perfectly.
Even when the WebView2 does not have scrollbars and the XAML panel (ListView) does have scrollbars, the mousewheel event seems to be triggered inside the WebView2 but never makes it to the XAML-Container.
(Setup for this is the same as my other WebView2 bug #4595)
Expected behavior
If the Webview2 content is entirely shown on screen without scrollbars, the panel/container should scroll.
Screenshots
This mostly shows the rendering issues I'm having (#4595), but maybe it helps?
webview2.mp4
Each frame is a ListView Item, title "Update *" is XAML TextBlock. Below which is a WebView2.

Additional Context
I guess I could work around this by creating the layout entirely in HTML and using only one WebView2, however this is a port from UWP and this worked perfectly before.
