In the Room Editor, slow clicking on an instance could cycle through overlapping instances

[nullbunny]

Is your feature request related to a problem?

I often find myself having to move instances out of the way and then back into place when trying to click on instances that are covered up by others.

It's even worse when I use "Select from any Layer" because most of my rooms have large area-style objects for things like camera zones.

Describe the solution you'd like

One of my suggestions was #7069 but I had another idea for cases where this doesn't work: Slow clicking on an instance could cycle through the overlapping instances, so you can just slow click until you picked the instance you're interested in.

Describe alternatives you've considered

See #7069
