I have an editor that occupies only a part of the total page. There are also a ton of hover tooltips (I really like the tooltip API in v6). However, these tooltips frequently expand farther than the edges of the editor itself – this is absolutely fine and actually makes use of the available space as much as possible.
However, especially for tooltips that contain actions, it is relatively annoying that the tooltips will close themselves if the user moves their mouse outside the editor’s area, but still inside the tooltip.
See the attached screenshot for what I mean:
(Disclaimer, I found that there was a relatively similar issue a few months ago: Fix for hover tooltip removed on hover when parent is outside of EditorView)
