Steps:
1. Create an Openshift application.
2. Edit this application and embedded more than four cartridge at one time.
3. Wait the result output page comes.

Actual result:
The vertical scroll bar doesn't work, and the cartridges information will show incomplete.
(In my case, there are 6 cartridges embedded and only showed about 4 of them.)

Expect result:
The vertical scroll bar should work as usual.
