Undo behaviour regression

[sm17p]

This is the editor.graphite.rs vs dev.graphite.rs comparision for undo.

1. Editor - Circle color undo's on first attempt
2. Dev - Circle color doesn't not change even after repeated attempts, (guess is all the color updates from picker are sent to the backend which creates a long undo queue)

Reproduction steps:

1. Create a circle
2. Change the fill color a few times
3. Click on the canvas
4. Undo

I'm only seeing two undo steps: the original click location upon starting to drag within the color picker, and the final color upon release. They don't get stuck. This is in dev.

Hmmm, I tried again, it worked as expected when the circle was selected.

However, when I clicked on the canvas after picking the color, undo got bugged. It then started functioning again after I re-selected the circle
