test case

validating http://websnippets.ru/article.php?id=30 (or the attached static copy of it) results in a good ">" character reference on line 33 getting misreported as bad. The actual bad character reference is "&w3" on line 48.

A minimal case that reproduces this problem -

  <!doctype html><title>test</title>&gt;<textarea>&w3</textarea>
  http://html5.validator.nu/?doc=data%3Atext%2Fhtml%3Bcharset%3Dutf-8%2C%3C%2521doctype%2520html%3E%3Ctitle%3Etest%3C%252Ftitle%3E%2526gt%253B%3Ctextarea%3E%2526w3%3C%252Ftextarea%3E&showsource=yes

An even more minimal case that shows what actually might be the root problem:

  <!doctype html><title>&w3</title>

  http://html5.validator.nu/?doc=data%3Atext%2Fhtml%3Bcharset%3Dutf-8%2C%3C%2521doctype%2520html%3E%3Ctitle%3E%2526w3%3C%252Ftitle%3E&showsource=yes

In that case, the validator fails to report any line+col numbers at all.
