Fix segfault on media playback in Chrome

Observed on both Chrome 79 and 83 on Ubuntu. Playing an inline audio,
scrolling away, returning and playing again causes the browser tab to
crash with a `SIGSEGV` error.

Error can be reproduced for audio elements that are connected to an
audio context.

* Play audio so the current time in the player state progresses.

* Unallocated the player causing the blank audio file of zero duration
  to be assigned.

* Allocated the player again with the previous file aga. Video.js
  updates the source only after a delay. So when we restore the
  current time in `applyPlayerState` the zero duration audio file is
  actually still loaded.

* Next time the player is played, the tab is likely to crash.

The added `browserBug` story repeats these steps until the error
happens.

Setting `currentTime` only after metadata have loaded appears to fix
the issue.

Add story to stress test allocating/playing/unallocating media
players.
