Whitespace before <head>

It appears that some sites use document.documentElement.firstChild and  
expect it to be the head element even if there was whitespace before the  
<head> tag.

Safari seems to drop whitespace before the <head> tag. Firefox seems to  
insert any whitespace before the <head> tag in the head element, even if  
it was also before the <html> tag or before the doctype, and it also does  
so with comments. IE seems to drop whitespace and put comments before the  
<html> tag as siblings to the root element and after as children of the  
head element. Opera currently does what HTML5 says, and it has caused some  
compat problems.
