User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:36.0) Gecko/20100101 Firefox/36.0 Build ID: 20150222232811 Steps to reproduce: Open web console and generate a popover window, for instance by hovering over a variable in the Debugger or (in the Inspector) by clicking on the EV tag to display event handlers for markup. Press CTRL+PAGEDOWN to switch tab. Actual results: Firefox switches tab, but the popover window remains on screen. Please see screenshots attached. Expected results: The popover window should have closed
