Seting dom.timeout.defer_during_load to false in about:config seems to fix this problem for me.

Seems likely a race in the page with a timer that expects to run sooner than we actually run it. Jesup any idea?

99% likely this is a bug in the page where they assume that 0ms timeouts happen before pageload occurs (which was never guaranteed); it does load images from the network in both cases.

Given that, closing the issue as invalid.
