Blocks inside inlines can, in some cases, cause larger numbers of CSS boxes to be present than the author probably expects, which I believe in some cases causes performance degradation. (I've seen cases in the past where such performance degradation was significant, although those cases may have been fixed in our implementation.) In many cases, the author intends the outer element to have block formatting. In the other cases, I believe the resulting formatting is non-tree-like, which confuses the mental model of the HTML element structure representing a tree. -David -- L.
