This is a known, long-standing bug in Opera. There are in fact a series of 
bugs to do with its handling of <head>. (This isn't even an ambiguity in 
HTML4, like most incompatibilities.)

For what it's worth, the WHATWG HTML5 spec does define this precisely:

Ian Hickson               U+1047E                )\._.,--....,'``.    fL       U+263A                /,   _.. \   _\  ;`._ ,.
Things that are impossible just take longer.   `._.-(,_..'--(,_..'`-.;.'
