I have HTTPS-Only mode enabled. For some reason, there is a bug on a server that causes a request to https://XXX/long.url... to be return an HTTP 302 to http://XXX/login.page....

This is the first request I have made to that origin, so maybe the strict-transport-security that is included in the response hasn't taken hold yet. What is most curious is that the subsequent request is upgraded by neither HSTS nor HTTPS-Only. I get the warning interstitial instead.

This is reproducible, but I won't share the URL publicly because I don't want to 0-day the server. I can share details privately.

Tomer, can you please investigate? I'll share a link with you privately.
