Memory leak and crash when clicking on "Skeleton" node in scene.

[Skalli]

tl;dr: When clicking on a skeleton node in certain scenes Godots editor keeps allocating memory until it runs out and crashes in mere seconds.

Godot version:
3.2.stable.mono.official

OS/device:
Arch Linux;

64-bit.

Issue description:
I noticed this when working with models from Make Human, it is reproducible with the steps done in the next section. But whenever I click on the Skeleton node in the scene hierarchy Godot eats up all available memory, then all available swap until it finally crashes.

How to reproduce:

• Create any model with Make Human (v1.1.1 if that matters).
• Export as *.dae (other options might work too).
• Import the file in Blender (v2.81a).
• Export from Blender as *.gltf to a Godot directory.
• Open the gltf in Godot and select "New Inherited".
• Save scene as *.tscn.
• Watch as Godot is frozen, memory consumption goes through the sky and finally crashes as no memory is available anymore.
• ...
• Profit?

Some pictures:

Click on Skeleton to cause memory leak.

Memory consumption in system monitor. Total is not correct because I killed the task to make the screenshot. Memory leak can take system down with it. It grows until it runs out of space.

Scene file used:
(Will attach shortly, right now it won't let me.)

Ah, true, I searched for the terms, but this issue didn't showed up. Sorry!
