Is it defined how the browser should behave wrt calling 
unrelated event handlers in user code during synchronous
XHR requests? (with "unrelated" I refer to events that are
not related to the ongoing synchronous request itself)

I didn't find statements directly addressing this in
but maybe there are indirect relationships between
specification sections that I am missing?
Or maybe it's deliberately undefined?

I ask because Firefox behaves differently to the other
popular browsers, in that it triggers event handlers for
other asynchronous XHR requests while blocking for a
synchronous XHR request.
