Oh boy. Right now, I am implementing a workaround for websockets in Safari on iOS 13 — apparently, they've somehow broken their already non-standard "x-webkit-deflate-frame" compression scheme and can't properly send fragmented messages anymore when it's enabled: they mess up the zlib stream at the start of the second fragment (or maybe at the end of the first fragment).
