Overlay / annotations get misplaced occasionally

I've not got any further in providing steps to reproduce this, but it did happen to me just now and I was able to deduce that the issue is occuring in ui/src/features/layout/previewOverlay/ViewportOverlay.tsx. It seems that updateRect() is either not being called, or being called and failing to correctly update the rect.

I've raised an MR that I hope will be more reliable, but it's hard to be sure given I'm not sure the exact sequence of events that cause the issue.

I was able to reproduce the problem on the MR. Attached video

Updated issue summary with the steps i used to reproduce.

Replacing with audio-free video

I was recording some demos of XB yesterday and was running into this fairly consistently when placing sections.

Hey @hooroomoo - could you please re-test.

1) I think the fix in the MR is still valuable
2) since this was last tested we introduced mutation observers elsewhere that have made the overlay generally more robust.

I don't seem to be able to reproduce the issue any more.

Tested manually and I also can't reproduce the issue anymore :D
