--- Comment #27 from Daniel Sweet <daniel.sweet at heyglide.com> ---
More on the freeze bugs I've been seeing, in addition to the Service Worker freeze bug:

I have been able to reliably reproduce freezing with a PWA that only embeds an MP3 using the <audio> tag. On iOS 13.6.1, if I play the file, then immediately (while still loading or under 2 seconds in) switch into another app, and then back into the PWA, I see the complete freeze after only a handful of switches. It's the same freeze as the Service Worker one: I can't move the page around, JavaScript execution is completely stopped, and the Remote Debugger doesn't receive any data from, nor can it send Console commands to, my iPhone.

I can't reproduce this problem on iOS 14 beta 6, but it would be ideal if we could get this resolved in iOS 13.x before iOS 14 is out, and without asking our users to necessarily upgrade to iOS 14 when it does come out. Especially considering that it was resolved in iOS 13.5 and regressed in iOS 13.6.
