Copied value's mimetype when browser extension is used

Is there a mimetype set when passwords are copied to clipboard with the browser extension? I started to use a GNOME extension called Pano which ignores passwords copied with 1Password app. However it cannot do it when the browser extension is used.

There seems to be a discussion with browser extensions here. If there's a mimetype being used, I can gladly communicate this to its developer. If not, can this be added, please?
