Arrays of Objects/Resources are impossible to edit in the inspector

Godot version

System information

Windows 10

Issue description

Because the inspector is polling, the property editor for the object is being created every single refresh (by default it is 0.2 seconds, in the video I have it set to 0.8 seconds and then change to 5 seconds to show the difference). The popup menu for object selection is impossible to select from since it disappears immediately (or, more accurately, every 0.2 seconds). I believe this is because the editor is instantiated again every single refresh, deleting the previous popup menu.

Note: in the video, I am only clicking to open the menu, I never click on any items to try select them. Every time the popup menu disappears, it is doing it on it's own. This issue is not apparent in the commit before #45879

This is adversely affecting work I am doing for another PR, which needs to use an Array of objects. If a fix for this could be expedited it would be much appreciated.

Steps to reproduce

New Scene > Add RichTextLabel > Try edit custom_effects

Try changing your refresh interval to be higher as well... at 0.2 seconds my popup menu basically didn't open at all, or just flashed up for a fraction of a second.

P.S. This menu is showing all objects in the menu, when it should just be showing RichTextEffect. That is another issue, described here; #40383 (comment)

Minimal reproduction project

No response
