Description

Security researchers Emil Ljungdahl and Lars-Olof Moilanen demonstrated that, in cases where the entire contents of a page are enclosed in a <div> with absolute positioning, a web forgery warning dialog won't be displayed unless the user switches tabs away-from then back-to the forgery page.
