Fixes #2002, mainly by removing the autoUpdate function which was being executed even when the tooltip is closed. I also removed floatingStyles when the tooltip is closed, and memoized the middleware object to avoid recreating it on each re-render.
Testing
Manually tested that the performance issue is fixed, with 6x CPU slowdown in Chrome devtools.
