What steps will reproduce the problem?
1. Go to http://codepen.io/anon/pen/pJLwYp
2. Notice how the containing <ul> does not actually contain it's <li> children. It's size is being incorrectly calculated.
What is the expected result?
The <il> children should be contained no matter how they wrap and no matter how many children are present.
If you look at the demo in Edge, it renders correctly.
What happens instead?
The containing <ul> does not fully contain its children.
