If you spoke for the maximum amount of time and got cut off, the
next time you tried to speak you'd just get the 'waiting for network'
state. Key repeats would cause more delayed state timeouts to queue
up.
We were using createRef() instead of useRef() in the hook, which
meant we were always creating a new ref object and never actually
getting the ref. This must have been working before the useEventTarget
stuff due to some quirk of React / hooks...
* Avoid also getting a 'mousedown' event by making the event listener
non-passive so the preventDefault() works
* Remember the touch that pressed the button so we only un-press
when that touch ends, otherwise the button gets released if the
user taps the screen anywhere else.
