look at the attached picture

When there are a lot of terms listed as all terms they do not fit in the box.

I found an old issue from 2008 discussing this but I felt a new one could be more appropriate since it was marked as fixed...

Solution:
change this

.tag-item{
  padding: 3px;
  margin-right: 8px;
  cursor: pointer;
  display: inline;
}

to this:

.tag-item{
  padding: 3px;
  margin-right: 8px;
  cursor: pointer;
  display: inline-block; /*this will make sure items are put in a new row if the box cannot hold it*/
}

SO this is more of a fix than an issue...
