[whatwg] fixBrokenLink is not defined

[Garrett Smith]

I have noticed over the last year or so, the error "fixBrokenLink"
often popping up.

  fixBrokenLink is not defined.

I seem to recall at one point filing a bug but cannot find it in w3c Bugzilla
http://www.w3.org/Bugs/Public/query.cgi

http://dev.w3.org/html5/spec/Overview.html

  fixBrokenLink is not defined.

The error can be a bit of a distraction when reading and discussing.

The WhatWG-hosted one-pager causes Firefox to freeze for upwards of
forty seconds; I'm not interested in that.

What is fixBrokenLink? Is it DOM-traversal done onload? That's a known
cause of such delay, and the larger the document, the longer the
delay. Although I do not know for certain if this is the case with the
spec on whatwg.org, "fixBrokenLink" seems a suspect possibility.

It would be a good idea to look into the cause of the problem and see
about using another approach.
