password entered into idmsa.apple.com doesn't work
I use the Firefox extension on all web sites, no problem, except for https://idmsa.apple.com. That web site pre-fills my Apple ID, and after doing cmd-. to enter my password, when I hit return, it always says my password was incorrect. If I copy the password from 1Password, then paste it manually into the field and hit return, I log in with no problem. I've tried repeatedly on different days (recently), but the result is always the same.
1Password Version: 7.9.2 (70902005)
Extension Version: 4.7.5.90
OS Version: macOS 11.6
