Seek Behavior Changed in 4.2.0

Seeking while playing audio now pauses. In the past, it would keep playing.

Wavesurfer.js version(s):

4.3.0

Code needed to reproduce the issue:

4.1.0 behaviour: https://codepen.io/sundays/pen/XWjZpxG

4.3.0 behaviour: https://codepen.io/sundays/pen/KKgQvwG

Use behaviour needed to reproduce the issue:

1. Click codepen for 4.1.0
2. Click play
3. Click on waveform to seek. It keeps playing.
4. Go to the codepen for 4.3.0, repeat the steps. The audio pauses when clicking to seek

The question is which is the correct behavior? Should seeking while playing audio cause it to pause? Or should it keep going? #2045 seems to have caused this.

Workaround to restore old behavior is to listen to the 'seek' event, check isPlaying(), and call play() yourself.

So when those lines are brought back, there needs to be a condition to skip them if the backend isn’t WebAudio.

Sounds good. Want to make a pr (since you “screwed up” 😛)?

I think MediaElementWebAudio should be extending MediaElement (as it is now), since it’s virtually the same, only feeding it into a webaudio node. Speaking of which, if we revert the changes from from #2045, it seems like those should be ignored by the MediaElementWebAudio backend as well.
