--- Comment #1 from Andy Davies <ad at andydavies.net> ---
This issue still applies in iOS 13.5.1 and Safari 13.1 on mojave

It's particularly bad if the HTTP/2 server doesn't support effective prioritisation as Safari makes the requests at a low priority but the server ignores this and responds, potentially blocking higher priority responses. 

See  https://andydavies.me/blog/2020/07/08/rel-equals-prefetch-and-the-importance-of-effective-http-slash-2-prioritisation/
