Thank you for your feedback. At this time we do not plan on fixing this issue.
Your feedback is very important to us, and it helps us improve the quality of
Internet Explorer. Unfortunately, we are currently unable to address this
particular feedback. We have addressed the crashing issue, but the page currently
results in a hang. We decided not to fix beyond this because the scenario
is narrow as it only affects invalid markup and our Watson data confirms this is
a rare issue.
It also does not occur in IE 7, 8, and 9 rendering modes (modern web page
standards). We continue to welcome more feedback, so please don't hesitate
to report other ways that we can improve Internet Explorer.
Best regards, The Internet Explorer Team
Is it bad for them to stop supporting IE6? If they created a patch for this and distributed it, why not just give the users the most recent version of IE that runs on their respective operating systems?
