v2.0.0-alpha.33

Fixes

• In v2.0.0-alpha.29 we introduced a bug where attempting to adjust the volume would just move the volume to one extreme. This would also have affected any other use of the ProgressBar component where the progress bar moved or resized on the page. This was all due to a mistake in a performance refactor for the progress bar, where we stopped correctly monitoring changes to the progress bar's bounding box. Since the volume bar first renders hidden, it had a 0x0 bounding box, and never updated.
