Undo behaviour regression

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
