Description of problem:

User reported:
When I try to select 2 CVs for comparison, I can’t click on “Compare
selected” button. 

In reality it is possible to click the button (although it is very difficult).  In addition once you click it, all package rows are blank

Version-Release number of selected component (if applicable):

6.1.0 beta

How reproducible:
Always


Steps to Reproduce:
1.  Create and publish two content views with the at least one repo in each
2.  Go to Content > Content Search
3.  Click 'Search' to search for content views
4.  Click the two checkboxes beside each content view
5.  Notice Compare "Compare Selected" is difficult to click.  You should be able to by carefully clicking around on the lower right corner of the button (Tested in FF and Chrome).  This will take you to the comparison screen
6.  Notice that the dropdown arrows are missing on each repo
7.  click on a repo name to expand it
8.  Notice that each package 'row' is completely blank


Expected results:

1.  Compare Selected button is easy to click
2.  Dropdown arrows are there to suggest each repo is expandable
3.  Each package rows correctly shows the nvrea and indicates when it is in a repo
