Edit in 1Password for Safari takes you to wrong item

By the way, what does happen if a user only has the browser extension installed and not the desktop version of 1Password (for iOS these are bundled, I think)?
What will happen if users click „edit“ in that case. Sine no application opens, will they be somehow made aware that they have to edit an item e.g. on 1Password.com website vault. Or will they just run into an error?
I can’t test this out right now - so I was just wondering how it looks in that case, usability wise.
