Popup: doesn't reposition when changing its context

[Wyverex42]

Bug Report

I have a shared Popup that is meant to be used as a tooltip. I explicitly don't want to have a Popup associated with all items on my page that can have a tooltip because this creates a LOT of popups and hurts performance.
So my solution is to use global state via /~https://github.com/diegohaz/constate to share the ref of the DOM node where the Popup should be opened.
Sadly, positioning the popup via the context property doesn't work correctly in my use case.

Steps

• Open https://codesandbox.io/s/vmm391vpv7
• Open the main popup
• Hover over any item
• A tooltip opens
• Hover over another item next to the first one
• The tooltip doesn't move
• Move the mouse to the border of the main popup so that the main popup stays open but the tooltip closes
• Hover over another item in a different row or column
• The popup opens in a new position

Expected Result

• When closing a popup and reassigning its context, the popup should be positioned at the updated context when it's opened the next time.
• The popup should point to the correct corner of its context

Actual Result

• The popup doesn't move when being reopened. It only moves if it completely disappeared first.
• The popup doesn't point to the correct corner of its context DOM element

I suspect I could make it work if I could somehow wait until the popup is completely gone until reopening it again. I've tried several combinations of state logic but none has worked for me so far.
Even then it will probably still have issues with pointing at the correct corner.

Sorry, but we don't have time to debug your code. It looks crazy and I'm completely lost in it 🦏
Can you please reopen issue with a minimal repro or update existing?

Ok, I've now spent close to another two hours trying to compress this example even more. Luckily I could get rid of constate and the hack. Also, you don't even need to nest the popup. This is as short as it gets:

The issues are still visible.

I can't reopen the issue though since you already closed it and I'm no collaborator.

Now it's clear to me, will try to find the root issue.
