Boris Zbarsky cf6ef6a24b Bug 1467437. Align with other browsers and the spec for whether hashchange and popstate events bubble. r=smaug
I think I caught all the places in our tree that add event listeners for these
events on a non-Window (and hence depend on bubbling behavior), but I'm a
little worried about what happens if webextensions do bareword
addEventListener() for these events...
