AbortError: The fetching process for the media resource was aborted by the user agent at the user's request.

Every now and then, when I cancel the currently playing audio in Firefox, I get an:

AbortError: The fetching process for the media resource was aborted by the user agent at the user's request.

on this line of the html5Unload function:

https://github.com/scottschiller/SoundManager2/blob/f432aa9ed96a0f9022e72fc4a1b977ba0643ed71/script/soundmanager2.js#L4195

Note that the comments within that function talk a lot about Firefox in particular.

It is a difficult to reproduce issue because it is flaky when this happens. Unfortunately, it happens often enough to be disturbing.

The problem is that I have difficulties catching that AbortError in React.

That AbortError is probably not expected by the SoundManager2 code either: There is still clean up code below that line that will never be executed, leaving SoundManager2 in an inconsistent state.

How can I catch this error in react-sound?

Any help is greatly appreciated.

Start at script/soundmanager2.js, particularly the html5Unload function around line 4195, and investigate the Firefox AbortError when cancelling currently playing audio. Reproduce the flaky cancellation if possible and determine how the error affects the cleanup below that line; done means the error is handled without leaving SoundManager2 inconsistent and the behavior is usable from React.
