What happened?
Dragging and dropping text within a WebView blocks the WebView from responding to mouse clicks when (a) HostInputProcessing is enabled, and (b) AllowExternalDrop is enabled.
To reproduce with the WebView2APISample (unmodified),
(1) Click Window > WebView Creation Mode > Windowed - HostInputProcessing
(2) Click Window > Create WebView
(3) Click and drag to select some text
(4) Drag and drop inside the WebView2
(5) Try clicking with the mouse inside the WebView2
Expected: after clicking, the selection should go away and you should be able to select other text
Actual: the selection does not change and you cannot cancel the selection or select anything else.
To prevent the problem, turn AllowExternalDrop off.
I was also able to reproduce the identical behavior in the WPF sample.
This is similar to but not necessarily the same as this issue:
#5141
In this case, there does not appear to be a way to restore normal operation of the WebView, and a single drag and drop operation within the control is enough to trigger the problem.
This is with version: 148.0.3967.83
Importance
Moderate. My app's user experience is affected, but still usable.
