Prevent ContextualToolbar of being displayed in specific places

[oskarwrobel]

I need to prevent ContextualToolbar of being displayed in some specific situation (when selection range intersects with some specific node). ATM CT displays always when the selection is non-collapsed and there is no way to configure it.

WDYT about adding beforeShow event to the CT plugin. This event will be fired after selection stops changing just before showing the toolbar. Other plugins will be able to listen to this event and modifies CT behavior eg by stopping this event what will prevent CT of being displayed?

A similar issue to https://github.com/ckeditor/ckeditor5-ui/issues/223 where the contextual balloon should not overlap the toolbar. IMO there should be a possibility to configure restricted zones (elements, in fact) which DOMRects should be avoided when positioning the balloon.

This, with an addition of an event, because such restricted zones may be dynamic, would be very useful. Just note that such event would need to provide the proposed location of the balloon in the event data to make actual sense.

Or maybe I misunderstood: did you mean to analyze the editing view document tree or visual geometry of such tree elements?

In my case, I need to analyze position of selection in model document.
