I use 1Password and work as a software developer primarily on web applications. I prefer to disable 1Password when working on something because of the code injected into forms (and the "network" requests that are made to load assets from the extension bundle).
The "Hide on this page" functionality does not work consistently at all. If I right click a text field and select the option it will disable the 1Password extension on that page...for a period of time. It always comes back after a few refreshes or some period of time elapses. I haven't been able to figure out a pattern exactly other than it comes back.
When this happens, I can right click a text field and see that the "Hide on this page" option is still checked - even though the 1Password extension is visible on the form field (see screenshot):
