1PW popping up where it shouldn't

In the WordPress Block (Gutenberg) editor, when choosing to rename a block, 1Password pops up in the input field where you edit the name.

I'm not sure why, because it's not designated as a password or login field in the HTML code.

You can see this at the Wordpress Block editor demo page here:

Steps to reproduce:

1. Click on the staggered 3 lines icon at the top-left
2. In the panel that opens, click on the 3 dots on any of the Group or Cover rows
3. In the pop-up menu click Rename
4. Observe 1Password popping up attached to the name field
