Copy component values to clipboard wrong

[vincentfretin]

Copy component values (values that are different from defaults) to clipboard is not working correctly for geometry and gltf-model, I get just geometry="", gltf-model="". For material component, I get all props with [object Object].
I didn't see an issue with my custom components.
The copy entity to clipboard implementation is correct for all three components.

I won't investigate this right away.
