1Password Sometimes Double-Fills Password Field

I have this issue too on multiple sites. This is the website I just had the issue with: https://moneybird.com/login
My flow and info:
- firefox latest update, 108.0.1, 1password 8.9.12, BETA channel, addon version 2.5.1
- enter the website in a new tab
- command-\ (my shortcut for 'fill')
- username and password fill both; in the password field I see the amount of stars corresponding to the length of my password
- within one or two seconds, the amount of stars doubles

Additional:
- 'inspect elements' after the 'doubling' shows it concatenates the correct password to itself, actually filling the field twice
- if i submit within the 2 seconds (i.e. before the 'doubling') login works fine
- This doesn't seem to be predictable - i.e. logging out, closing the tab, doing it again doesn't always show the same behaviour
- I have this on multiple sites
- If I do command-\ again after the doubling, the original password gets entered again, and the doubling does not occur

Hi @nickfromdc,

Thank you for confirming this.

I have tested the AWS gov site and I can't seem to replicate the behaviour. Can you let me know the steps you are taking to fill? Are you clicking on the item beneath the field or are you using a keyboard shortcut?

Any information would be really useful.

@Joy_1P it doesn't happen on every site, but I have noticed it on a few. I do see it pretty consistently on the AWS gov site (https://signin.amazonaws-us-gov.com), but I have also had it happen on a few other sites. I upgraded to 8.9.8, and the behavior still occurs.

By "fills twice" I do mean it fills the password field twice. The behavior is it: 1P fills the form, there is a brief delay, then 1P fills the password field again.

Hey @nickfromdc, does this issue happen consistently on specific websites or does it happen randomly? By double-fill, do you mean that 1Password fills in the password twice in one field? Or does 1Password fill the password in two different fields?
