Actual behavior:
GIVEN I opened a protected page on a client wiki AND I am a logged in user with sufficient permission to edit it (so that edit pens are indeed shown) AND I wait long enough / perform an action in another tab to be logged out WHEN I click on a bridge-enabled link THEN I am presented with an APPLICATION_LOGIC_ERROR ("Error: Data Bridge should never have been opened on this protected page!")
Expected behavior:
Unsure. Do we have a permutation of ErrorPermission to deal with this (I doubt it)?
