Open popup as new instance of ChromiumWebBrowser in WinForms

[GITMoor]

Is there a way to implement something like this but instead of ChromiumHostControl return a new instance of a ChromiumWebBrowser? The problem is that when you open a pop in a new tab of EasyTabs the popup is conected to ChromiumWebBrowser from witch it was opened, and if you torn tab into a new window the popups opened from that popup will appear in the torned window where ChromiumWebBrowser is located. Here is a vid of problem

How would hosting the popup in a ChromiumWebBrowser instance change this behaviour exactly? Sounds like an implementation detail of how you've implemented the tabs.

Since then i did some investigation, and now the problem is solved. But i have one more question. When closing window with ChromiumWebBrowser to prevent ChromiumHostControl's stop working im setting its parent to null, but how can i know when all popups being closed to dispose ChromiumWebBrowser later?

You'll need to keep a count of open popups, increment count in OnPopupCreated, decrement count in OnPopupDestroyed.

Nothing publicly accessible at the moment. There's a dictionary internally, it's deep within the C++ side, something we could potentially expose in a controlled way.

PR's welcome.

Alternatively LifeSpanHandler could be improved to keep count and provide the number of active popups in OnPopupDestroyed or something similar.
