Summary:
Fix performance issue in rendering sidebars

Noticed during debugging that sidebars are continuously re-rendering if the mouse is on top of them, which is caused by the mouseMove handler of resizable containers always updating the state with a fresh object, causing a render (see yellow rectangles in test plan). Short circuited this by checking if the resize state should actually change and bailing out otherwise.
