What happened?

What happened?
Using WebView2CompositionControl within a wpf application. After clicking print, none of the dropdown boxes allow changes using the mouse.

Notes:
Arrow keys and enter allow selection changes.
There is no problem using WebView2 instead. However this is not possible because of the airspace issue.
