Fixes #3977
Fix issues on the
AudioContextnot being properly resumed, especially on iOS 15. This is done by explicitly calling.resume()on theAudioContextwhen required. Extra checks were added to make sureresumeis only called when the window is being re-focused, and the state is going fromsuspendedorinterruptedback torunning- otherwise exceptions are thrown. Additionally, if for any reason the context can't be resumed successfully, the Auto-Play event listeners are re-bound so that the audio can be resumed later.Documentation:
