When I was playing around with this last year I encountered similar
issues with "stateful" gtk widgets. Since I primarily cared about the
webkit widget, and since that's still the only really implemented
widget, I found that forcing there to only ever be one emacs window
displaying it was the best compromise between technical limitations
and what I think of as "the emacs paradigm" for displaying such
content. Although Po seems to disagree with me on that point, hence
his pushing forward with the offscreen rendering technique, although
there are still various bugs to be resolved in that implementation.
