Same problem on winXP and current trunk.

Since Bugzilla sends an HTTP header specifying the charset, you have to load the testcase locally to reproduce the bug.

[Henri Sivonen (:hsivonen)]

The script running twice in some cases (did test with this exact amount of padding) is HTML5-compliant and still happens with the HTML5 parser.

Based on what I've heard from a WebKit developer, WebKit doesn't do this. If we believe that it's good enough to scan the first 1K of the page and commit to an encoding at that point (what I hear WebKit does), let's escalate to the HTML5 spec to get reparsing removed from the spec. OTOH, if we believe we need to take a late meta charset into account in order to be competitive with IE, WONTFIX.

Bulk-downgrade of unassigned, >=5 years untouched DOM/Storage bugs' priority.

If you have reason to believe this is wrong (especially for the severity), please write a comment and ni :jstutte.

Not a duplicate of the bug this was marked as a duplicate of but a WONTFIX instead.
