[Drawer] Allow clicks under closed persistent Drawer

[gla3dr]

Stops right-anchored persistent drawers from intercepting the mouse when
they are closed.

Tested fix in docs:

persistent-drawer-bug-fixed.mp4

Fixes #29997

• I have followed (at least) the PR section of the contributing guide.

As I was the one suggesting the changes, I would wait someone else to review the PR :)

This solution looks ok to me.

Side note:
It's a bit weird that the Drawer renders a wide element even when it's closed. Perhaps we can change it to collapse entirely in the future, so the problem solved by this PR would not exist at all (this would be a breaking change, though).

this would be a breaking change, though

This was my biggest worry, but I agree. Should we add it to our v6 milestone?

There are broken screenshot tests, looks like this is not the most ideal solution to the problem. We will need to investigate more and see what would be the best fix for it.

I am closing the PR, we can re-start the effort once we find a better solution to the problem
