Description
UI Blocking occurs when mouse up/down event occurs on MFC Control (Tab control) above WebView2.
However, hiding the window and showing it again solved the problem.
What causes these problems?
I am using vs2015, and it is a project created based on a MFC dialog box.
Version :
Microsoft.Web.WebView2 (1.0.864.35)
Microsoft.Windows.ImplementationLibrary (1.0.190610.2)

Research direction
Start with the attached video and reproduce the mouse up/down behavior on the MFC Tab control above WebView2 in the reported MFC dialog project. Check whether hiding and showing the window consistently clears the blocked UI, using the listed WebView2 and Windows Implementation Library versions; done means identifying the cause or a confirmed resolution.
