Consider preventing overflow of replaced elements

[kripod]

In the unreleased modern-base stylesheet, there are rules to normalize the behavior of replaced elements like img, video. svg, iframe, canvas and audio. According to the related issue of normalize.css, one of the reasons behind not adopting these rules is that it can "trigger certain bugs in IE 8", which modern-normalize doesn't support.

On the other hand, I would be interested in use-cases where applying max-width: 100% causes undesired behavior for replaced elements.
