Steps to reproduce the issue

Go to Help -> Joomla Help in the Admin menu
Scroll down to the bottom of the list of Help pages
Click one of the Users links.

Expected result

Something happens

Actual result

Nothing appears to happen because the iframe containing the Help page is out of sight

System information (as much as possible)

Additional comments

I made the div containing the index the same height as the iframe and scrollable with this inline style:
style="max-height:2100px; overflow-y:scroll"
which appears to do what I need

I have been using this page a lot and this scrolling is driving me nuts! I previously raised an issue suggesting a Javascript solution. I think this is better. I will close the previous issue.
