Bug 21381 – Incremental parsing of html causes bogus line numbers in some cases

• Status: RESOLVED
• Resolution: FIXED
• Component: DOM

[Oliver Hunt]

When incremental parsing of an html document pauses midway through a <script> element, reentry to the parser resets the script start line number, leading to somewhat borken behaviour.  Originally reported by Tim on bug #20187 but it turned out be an unrelated issue.

(from tim's comment:
With the fix for bug 19053, this bug can be seen on webkit.org. Just attach the
debugger, pause and reload the page.

Fixeration, but no layout test

I haaven't been able to make a layout test, but i'm sure it should be possible.  I am going to see if weinig can help out -- however the patch itself should be reviewable.
