Developer Console displays empty gray window in all browsers online showcase

Hi Isomorphic,

bringing up the online showcase and the Developer Console in FF26/GC43/IE11/Win8.1 results in a gray screen for me.
Result is the same for the bookmark approach and the Link in the showcase.

It does work in my application, though (my application: v10.0p_2015-05-21).

See screenshot. Version should be Jun-15 (see 2nd screenshot)

Best regards
