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.

flipper-plugin
flipper-plugin is the dependency used by all modern Flipper plugins (project "Tommy").
For background: https://fb.quip.com/YHOGAnaPqAVJ
flipper-plugin is to be used as dev and peer dependency of all Flipper plugins. It provides:
- (TODO) Standard API's to interact with Flipper, such as the client connection.
- (TODO) Standard components to organize the UI
- (TODO) Testing utilities
API's provided by flipper-plugin are documented at fbflipper.com (TODO).
There should normally be no need to install flipper-plugin as dependency.
Rather, plugins should be scaffolded using npx flipper-pkg init (TODO) as documented here
