@skip 
Scenario: autocompletion of a pattern that matches regular existing groups but also a group with whom the item is already shared (folder)
  Given user "regularuser" has logged in using the webUI
  And the user has browsed to the files page
  And user "regularuser" has shared folder "simple-folder" with group "finance1"
  And the user has opened the share dialog for folder "simple-folder"
  And the user opens the share creation dialog in the webUI
  When the user types "fi" in the share-with-field
  Then all users and groups that contain the string "fi" in their name should be listed in the autocomplete list on the webUI except group "finance1"
  But only users and groups that contain the string "fi" in their name or displayname should be listed in the autocomplete list on the webUI
  And the users own name should not be listed in the autocomplete list on the webUI
