Blue Screen for OTP Prompt in Browser

When using the quickfill feature with FireFox for iOS v144.1, filling in the username and password works fine. When I am prompted for a OTP and click on "1Password" in the password selection menu, the screen turns blue for 2-3 seconds, after which I can touch the screen to review the browser page w/OTP prompt again. 

Screenshot of the issue. The entire Firefox browser window is replaced by the blue square.

Environment:

• Firefox for iOS v144.1
• iOS v18.7
• 1Password for iOS v8.11.14

I can open the 1Password app to copy and paste the OTP from there, but it would be nice to use quickfill again.
