[Problem/Bug]: Copy/paste functions not working with touchscreen

What happened?

When I select text within a page displayed in the WebView2 control, the menu for selecting "Copy" appears but I'm unable to click on it. It just stays open until I click away. The text doesn't get copied to the clipboard as I'm not able to paste it inside or outside of the app. Selecting Ctrl+C using the touchscreen keyboard also fails to work. If I use an external keyboard or a mouse, it works fine.

Importance

Moderate. My app's user experience is affected, but still usable.
