I like the idea, it would be great if it can be done with Popover API as you mentioned in comment#549

From your point of view on the Popover implementation for handling visibility of dialogs, I thought it would also be a great enhancement towards tooltips, I've been experimenting with it recently in a Codepen example

Yes exactly! I think that would make a lot of things easier in future. Also there may be added anchor positioning which is already working in chrome but not firefox and safari yet. Maybe we could use a polyfill.
