Could you upload a minimal testcase
(note, in certain cases webkit/blink based browsers don't have document.write and session history the
way it is specified in HTML spec so this might be related to that).

So document.write in that timeout creates a new window object, and you set listener there.
Then back goes back to the previous window/document-before-write and possible
events fire on that window, not the window object which was created when 
document.write was called.
This is exactly the case where webkit/blink don't follow the spec, so you'll get different behavior there.

As far as I see this is invalid.

>and possible events fire on that window
no, it's not firing anywhere and I don't see a way for onpopstate event to possible be triggered after execution of document.write(), here's testpage where event listener is set to window before doing document.write()

Ok, I can see a problem.
Well two problems. The spec has changed (again) after popstate was implemented so
popstate dispatching should be async and SharesDocumentWith doesn't seem to do the right thing
always.
