Have you looked at this thread:

your issue sounds similar.

Is one backend the default_backend (where HTTP/2 requests go) ?

Does it work with something like:
use_backend %[req.hdr(host),lower,regsub(:\d+$,,)]
or
use_backend %[req.hdr(host),lower,word(1,:)]

That issue with the port being part of the host header for Firefox Websockets should already be fixed in HAProxy 2.4.4.
