seek is ignored while loading

[nt4f04uNd]

Which API doesn't behave as documented, and how does it misbehave? when trying to seek in the loading state, it's ignored

Minimal reproduction project sorry, i don't have time to write one at the moment, i hope you will understand if you absolutely need it to fix this i can find some time later to create it, but i more likely will make a pr fixing this myself

To Reproduce (i.e. user steps, not code)

1. have a player in loading state
2. seek

Error messages no

Expected behavior seek should be performed no matter what the state is

Screenshots here's a video from my app

Seems like the same issue, seek didn't work but after adding await audioPlayer.load(); seek started working again.
