End-to-end encryption sample crashes in Safari

[vitaly-castLabs]

Browser affected

Both regular Safari 16.0 and Safari Technology Preview, Release 154 (Safari 16.0, WebKit 17615.1.6.2) on macOS 12.6, MacBookAir (M1, 2020). From npm logs (when I run it locally): "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/16.0 Safari/605.1.15"

Description

https://webrtc.github.io/samples/src/content/insertable-streams/endtoend-encryption/ causes Safari to throw "This page was reloaded because a problem occurred"

Steps to reproduce

Open the sample page, type in some Crypto key in the box, press Start and then Call

Expected results

Garbled video in Middlebox

Actual results

The page apparently crashes and Safari reloads the page.

I see about a dozen "send" and "recv" records in the JS console with both audio and video (key & delta) present, i.e. it works for a little while before crashing.

When there's no crypto key specified it works flawlessly. Works fine with Chrome, both crypto/no-crypto scenarios

@youennf should this be reclassified as a Safari bug?

Looks like a Safari bug indeed. It works for me on Safari TP 153:

Yes, @vitaly-castLabs, can you file a bug in bugs.webkit.org? I'll file one otherwise.

@youennf Done: https://bugs.webkit.org/show_bug.cgi?id=245870

@saghul it works for me on my old MBP (macOS 10.15.7, Safari 15.6.1) too, it's just unbelievably slow (I guess this is the issue: https://bugs.webkit.org/show_bug.cgi?id=229190) when encryption is on

Thanks for the reminder on bug 229190, I'll fix it.
