Description
What happened?
When two WebView2 browser windows are created within the same application, and you open (*) a tooltip in one window and then hover over another window which also opens a tooltip and then lose focus, then one of the two tooltips remains active on the screen on top of any other application, until the application itself is closed.
This is very annoying to our users as now they have tooltips floating on their screen as long as our application is active.
(*) A tooltip is in this case opened by hovering over an image with a title.
Importance
Important. My app's user experience is significantly compromised.

Repro steps
This issue can be reproduced as follows with the included test project. Please also see the attached video showcasing the issue:
- Run the application and click twice on the 'Open WebView2 Form' button, this will open two forms containing
WebView2instances. - Make sure these forms overlap.
- Activate the tooltip in the first form by hovering over the image.
- Now activate the tooltip in the second form by hovering over its image, note that the tooltip of the first form won't disappear.
- Lose the focus of these forms.
- Observe that the tooltip will remain in place on top of all other windows, until the application has been closed.
