When you change color property and close the color popup, the property is set twice upon close

[KoBeWi]

Godot version:

Steps to reproduce:

1. Add a Node2D
2. Click to change modulate property
3. Change it to different color
4. Press Escape

First set comes from clicking color, two latter sets are from closing the popup.

This was briefly fixed by #44895, but #45042 reintroduced it. This is very low-priority issue (it was there perhaps since last inspector rewrite and no one reported it) and doesn't really affect anything, but it's strange and redundant that the value is set twice.
