Go to https://libwebsockets.org/testserver/
Click "Send junk"

Chrome and Firefox don't terminate, Safari does.

When clicking the "Send junk" button it sends a text frame like 'aaaaaaaaaaaaaaaaa...'  and in SocketStreamHandleImpl::readStreamCallback I get kCFStreamEventEndEncountered.  The NSURLSession WebSocket implementation also terminates.

I can easily reproduce the behavior reported by Alex Christensen. Just go to https://libwebsockets.org/testserver/ and click "Send junk". This also has a real world implication as described here:
