fix(web): Avoid stutter when starting playback

[blaugold]

Description

Setting currentTime of AudioElement after calling play can cause a stutter, if the browser is able to start playback of the audio immediately and execution after play is delayed by other tasks in the event loop.

By setting currentTime before calling play this issue can be avoided.

I wonder if it's also solved with #1469. Because there it waits for the onLoad operation to finish. But could be another case :) Maybe you can try :D

[blaugold]

I'll try it out :)

[blaugold]

OK, I've tried #1469, and while it does make the issue I'm having less likely it still happens sometimes.

@Gustl22 Friendly ping. Is there anything else I need to do?

[Gustl22]

I'll also try your branch ;) But I also wonder, what is the technical reason to avoid stutter, when setting the position before playing.

Edit: never mind, I get your point. Will test and merge ASAP. Thx ;)
