lacking bottom margin under issue listing description

To explain the lay-out problem, please go to https://drupal.org/project/project_module

Under the list instructions ....

Extend and customize Drupal functionality with contributed modules. If a module doesn't quite do what you want it to do, if you find a bug or have a suggestion, then join forces and help the module maintainer. Or, share your own by starting a new module.

....there is not enough or no margin. At first sight I thought that the title header of the first module in the list went missing. Then I discovered that I did not see it because it seemed too much part of the list instructions. There should be a clear separation between the instructions and the first title, to make clearer where the list starts.
