Small logic cleanups (#3449)

* Small logic cleanups

* Small logic cleanups (#3451)

* remove a few things

* oops

* stop swallowing the error

* queue callbacks

* oops

* log error if caught

* no need to be nullable

* move isClosing=true up

* reset `isClosing` and `closeCallbacks` on close completion and open

* run queued callbacks on `open` if there are any pending

* rm unnecessary ref and check

* ensure order of calls is always correct

* call `snapToIndex()` on open

* add tester to storybook
