Key icon for animation player not displaying

[malkav182]

Godot version:
Godot V3.2

OS/device including version:
Ubuntu 19.10 eoan

Issue description:
The key icon from the animation player is not displaying in other nodes (only displays the icon in the animation player node properties itself). It only displays if you close the animation menu and open it again. Pretty much similar to #18929 case.

Steps to reproduce:

1. add an animation player.
2. add a property track, like a sprite position.
3. click in the other node (this example, the sprite node). None of its properties will display the key icon
   4). close the animation player menu and open it again.
4. check the other node again. It will display the key icon.

cc @guilhermefelipecgs, as they fixed it last time the bug was known to occur.

Looks good in v3.2.1

Greetings i can still reproduce this error in 3.2.3 stable in steam

Edit:
I investigated a little more. I did manage to get the key to appear as shown in the gif above. However, if the region option is enabled the key disappears when another node is clicked as shown in here:

Edit 2: Just noticed that there is a window control menu at the bottom of the screen and when I select the TextureRegion option the key icon disappears. Don't know if this is by design but it seems likely because if I am in the TextureRegion editor I can't see the animation editor

I'm quite sure that this happens because of the texture region editor overriding the animation one, a bigger problem that has a lot of issues opened about it already (e.g. #28341). So I will just be closing this.
