This issue has been transferred from the Kibana repo since the issue it is related to the UI data grid.

I believe this issue has a similar cause as #5476 and should have been resolved by 8a035de. This is not yet in latest Kibana main but should be in the next EUI upgrade. Closing for now, please feel free to re-open or open a new issue if it's still present afterwards.

Actually, nope, I was totally wrong about the above, sorry - the key here the reproducing is to click a header cell when another header cell's popover is already open. I'll have a fix for this shortly.
