Moving VisualElement results in lost Hover state

Trying to implement runtime tooltips (2020.3.4f1 + UITK 1.0 preview14, multiple platforms). I've run into an issue whereby if I set an element's position (either .transform.position or e.g. .style.left), the rest of the UI immediately loses the hover pseudo-state that it had. If I delay the movement, the hover state persists until the move is executed.

I guess an element move is somehow causing a canvas redraw without then re-applying the hover state? This prevents getting runtime tooltips up and running and is a real nuisance for us.

I'm happy to file a bug but as this could manifest itself in many different ways I wanted to check if this issue is already known?
For various reasons we are keen to stay on 2020 lts for the meantime - so if it's something fixed in 2021 we'd super appreciate a backport.

Many thanks for the team's work as always.

 

You're a super star, many thanks
