<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>HTML API: Step past closing HTML, BODY tags
The HTML specification does not close HTML or BODY tags (pop them off the stack of open elements) when their tag closers are encountered. The HTML processor correctly handled this behavior, however it incorrectly "paused" by returning true from the step functions.
Props jonsurrell, dmsnell, gziolo.
