On a site where there are multiple saved logins in Bitwarden, autofillling via the CMD+SHIFT+L shortcut works OK, however, when the usernames are not human recognisable I must select which entry to autofill from the extension UI near the URL bar. Clicking on an item in Firefox+Chrome autofils the selected entry into the webpage, however in Orion (both beta and RC) this results in the attached error. 
As implemented in Firefox & Chrome, the item selected should autofil into the page.
