Short description of error
Picking a color to paint with isn't registered with undo, therefore when undoing a stroke with new color, the color change is also undone.
Exact steps for others to reproduce the error
- Create a new scene.
- Select the cube and enter vertex paint mode.
- Pick a different color.
- Perform one stroke (i.e. click).
Expected: stroke is undone, new color selection remains.
Current: stroke is undone, color selection is also undone.
