memory profile iOS 17.5

I have noticed that audio sprites when played are not released for garbage collection and result in the browser tab resetting. This is only happening in iOS 17.5 beta. All previous iOS release did not have this issue.

This issue can be seen here:

https://www.macguffinandshemp.com/iOS17test/

if you open this page in chrome or safari on iOS17.5 beta and click on the button labeled "audio sprite loop" you can see the memory rapidly increase and resulting in the browser tab resetting.

This issue is also happening using howlerjs and this demo has been created:
