Extension tries to fill Generic Text Fields, Should it?

HI, have been noticing this anomaly more and more often in the last couple of months - and it's consistent on Windows & macOS. See image below for an example where I was replying to a comment here on this forum and the 1PW Browser Extension prompted to fill the post comment field with my 1Password Account Log On details... Is this normal behaviour (due to the autofill functionality and fields not always being tagged correctly on websites) or should it not be prompting like this? Getting this in Brave on both a PC and my MacBook Pro.

1Password Version: 8.9.10 (Win) & 8.9.11 (Mac)
Extension Version: 2.5.1 (both)
OS Version: Win 10 (21H2) 19044.2364 & macOS 12.4
Browser: Brave 1.46.144 (Chromium: 108.0.5359.128)
