[Problem/Bug]: Webview2 WPF rendering issue with 2 screens

[harshmodhiya]

What happened?

If we have 2 screens with different scaling, we can see a rendering issue in the Webview2 control.
The window may freeze, preventing users from clicking anything, moving the window, or closing it.

We can reproduce this issue with 2 cases:
Case 1:

• Open the WPF-created application in the external screen.
• Disconnect the external screen
• Open a dialogue or screen which have the Webview2 control
• Try to move the window around or try to click X(close button)
• The users can't move or close the screen

Case 2:

• Open the WPF-created application in the default screen.
• Connect the external screen
• Open a dialogue or screen which have the Webview2 control
