It would be nice to report HTML5 'parse errors' to the error console if the perf characteristics don't turn out to be awful.

This would help resolve the issue in bug 499246 regarding the parsing of invalid HTML tags, e.g. self-closing HTML tags on non-void HTML elements, e.g. The script tag, <script src="..."></script>, which is a raw text element and is invalid when presented in a self-closing format, <script src="..."/>.

Currently, when the invalid self-closing tag of the raw text element "script", i.e. <script src=".."/>, is encountered, Firefox presents an empty display with no error in the error console.

It would be beneficial to know that Firefox croaked on display when attempting to parse the invalid tag.

Isn't this the same as bug 878364?
