I've implemented help for a custom field using the tip in:
https://confluence.atlassian.com/jira062/creating-help-for-a-custom-field-588581961.html
When I configure this using Gear -> Issues -> Custom Fields -> Gear -> Edit
and paste in similar code into the Description field, I notice that the change takes effect on the configuration page, but not anywhere else in JIRA.
Specifically when I am editing an Issue, clicking on the help icon next to the custom field does not work. I noticed on the rendered page that there's no <script> tag generated.
The help icon works correctly for other fields, but they are not custom.
Any help on this would be appreciated.
