Fix error if the same "undo" is clicked twice in succession. (#10340) * Fix error if the same "undo" is clicked twice in succession. This change disables the button once it's clicked, so that clicking it again won't do anything. Previously, it would result in an "move index out of bounds" error dialog shown.
