Description

<!DOCTYPE html>
<html>
    <head>
<title>Page Title</title>
    </head>  
<div id=red"
</div>
<div id=blue>
</div>
<div id=yellow>
</div>
<div id=black>
</div>

Not only does this not throw a validation error, but nothing after the id=red" line is validated at all.

Research direction

Use the HTML example as the reproduction and start by locating the validator entry point responsible for parsing attributes. Add a regression test for the missing opening quote, then verify that it reports an error and continues validating the later elements instead of ignoring them.
