I work in a company where I have two okta accounts (because hey, why not) on two .okta.com subdomains.
Bitwarden _randomly_ messes up the two subdomains and most of the times (but not always, which seems strange actually), it fills the form with the wrong password. I don’t know why. I know that there is an option to make it stricter on domain matching but you can’t configure it on per item basis, only for the whole vault.
