Item12958: HTML in a label can break the editor

Given a formfield definition such as:

| <h2>Comments</h2> | label | | | | |

when you try to edit the topic, tries to link to the topic <h2>Comments</h2>. normalizeWebTopicName breaks this down as web=<h2>Comments< and topic=h2>. The web name validator then refuses to deal with this web name and returns undef, and the crash happens. Oh, and it tries to use {web} which is not a field in a Form.

Fix is to ensure a valid web name is always found:

HI Crawford, can this be checked in? What is it waiting for, and is there a unit test for it?

-- GeorgeClark - 21 Jul 2014

There are no unit tests for any part of the edit script, AFAICT. It has been tested in a live site, however, and can be checked in IMHO.
