Description Simon Pieters (:zcorpan) 2016-04-06 03:43:52 PDT 
The HTML spec says

> If current node is a pre, textarea, or listing element, and the first child node of the element, if any, is a Text node whose character data has as its first character a U+000A LINE FEED (LF) character, then append a U+000A LINE FEED (LF) character.

This is because otherwise it doesn't round-trip correctly if the data starts with a LF.
