[Problem/Bug]: WebView2_11.remove_ContextMenuRequested returns ERROR_INVALID_STATE

[sane-git]

What happened?

Hello dear WebView2-Team.

We're running a CDialog derived (MFC) application which hosts an instance of the WebView2 control.
During initialization of the WebView2 control we add several event handlers such as handlers for NavigationStarting, NavigationComplete and among others the ContextMenuRequested event.

In the dialog's OnDestroy message handler we do cleanup all that pertains to the WebView2 control including the removal of the event handlers mentioned in the previous paragraph.

The removal of the ContextMenuRequested event handler, however, leads to an ERROR_INVALID_STATE exception in the WebView control saying that The group or resource is not in the correct state to perform the requested operation.

Can you please take a look into the problem. A demo project is attached to this ticket.

@sane-git I checked your app and the problem that I found was you were closing the controller before deleting webview2. Controller owns CoreWebView2 so it should be deleted once CoreWebView2 is deleted.

This solves my problem.
Must have missed this particular statement in the documentation.

Thank you very much for your support.
