As reported in #48893 (comment), it seems that it happens only when the popover contains a tabbed interface (e.g "Solid" and "Gradient" tabs for the background color, or "Default" and "Hover" tabs for the "Link" color). Maybe this could help to narrow down the issue.

For more context, the Popover in question is part of the Dropdown component. The Dropdown component should set the anchor for the Popover component (the anchor should be the individual item group).

If it happens only for the tabbed interface, I'm guessing that maybe the "width" of the popover is not right (probably 0) at the time the position gets computed causing the wrong position. So some kind of race condition where we don't update the position based on the right width properly.

#49368 seems to have fixed this issue, closing now
