There are some forms I access often that have no username field. Just a password field and a submit button. Naturally, my 1Password login entries for these forms contains no username and just a password.
Since a few months ago, whenever I try to auto-fill one of these forms using the keyboard shortcut Ctrl+\ with the Firefox extension on Windows 10, 1Password fills the same password twice in the same input field, with a space in between.
For example, if the password is "foobar", the input field gets filled with "foobar foobar". Obviously the login fails.
When I manually copy the password using the extension UI, the correct value gets copied to the clipboard.
