Account password required for browser extension

In Safari, I was today presented with these two screens (one for Facebook, one for my credit union):

On each, note that I clicked in the username field, didn't see 1P(mac) offer the matching item from my archive, clicked on the "locked 1P" icon in the username field, and was presented with the 1P(mac) "enter password" window.

I realized on one and confirmed on the other that, while I could have entered my 1P(mac) password, I could also click back in the username field and press ⌘+\, and 1P(mac) filled and submitted the page as expected.

I hope this helps you figure out what's going on, even if it's just that I'm "doing it wrong."

...and now, of course, 1P(mac) is working as expected—either offering Touch ID, unlocking itself with just a click on the "locked 1P" icon, or not asking to be unlocked at all (even though the icon indicates that 1P is locked)—on both of those login pages.
