After autofill in Firefox/Chrome my MacBook Pro automatically switches app to Safari

I use Safari, Chrome, and Firefox all day long. When I am using 1Password to fill username and password on a page in Chrome or Firefox, it regularly fills these in and then switches to Safari. What I mean by this is that the equivalent of me Command-tabbing to Safari occurs. It does not cause Safari to load the same page or try to log into something, it just switches to the Safari app. I also use Spaces, so this often results in changing to a different space on my computer as well. I have to Command-Tab back to Firefox or Chrome and press Enter to complete the login process. Any ideas as to what might be causing this?

1Password Version: 8.7.1
Extension Version: 2.3.7
OS Version: 12.4
Browser:_ Firefox
