Reusable element within a repeating group strange behaviour

I have a reusable element which includes a Group Focus. This all works as I’d expected except when the group focus is visible within the reasonable element within the repeating group and the pages issubsequently scrolled. The Group Focus renders in the top left of the page and remains there until I refresh the page.

Just wondering if anybody has experienced similar or alternatively has a workaround?

can you share a video of the behavior, from the point that the reusable element in the repeating group is clicked to open the group focus, and perhaps make your editor viewable so somebody might be able to take a look and attempt to help diagnose?
