torbrowser stream isolation considers domain:443 different from domain:444

torbrowser isolates domain:800 from domain:80. This is inconvenient when domain:800 checks whether the request matches the IP seen by domain:80, especially as there is no way to disable stream isolation.

Tor Browser does not isolate base on ports. The IsolateDestPort option is *not* set, and the domain isolator doesn't look at the port at all when it generates/retrieves the auth based isolation nonce.

Eg: via http and https use the same circuit.

The only thing I can think of that's happening is that you really do happen to mean "port 800" which isn't a commonly allowed destination port. If you used an Exit that allows port 80, but does not allow port 800, then the tor daemon has no choice but to create a new circuit with a more suitable Exit for the 2nd request.

This is totally orthogonal to isolation (which should be/is doing the right thing), and boils down to Tor Browser not being clairvoyant.
