Definitely agree on how annoying that is, but as far as I know no one has really pulled off client side rendering in any way looking even close to equal on all browsers and platforms. I know I spent years on another project trying to do just that before resigning to render the final result (PDF in this case) server side - so at least _that_ was consistent, albeit unfortunately not with the expectations one has from having seen the client side rendering before.
