That's good. It'll be nice to get this sorted,
and hopefully it may make some things work more as expected (I'm not sure what
currently happens if js expects the inner html to be present in the current
page, but that'll no longer be an issue hopefully).

What kind of "foundational changes" are being made,
and will the multi-pass rendering logic be able to also handle other js-made
dom changes or is it going to be more like altering the html string in memory
then re-rendering that?
In addition, will the dom be altered by the presence of this html whilst the script is
running or will the script run then the new html be parsed and linked in?
I'd think the first is the expected behavior, but I'm not sure.

Cheers,
Adam.
