Bar tab requires pinch zoom to see icons properly
I have a view which has 3 icons at the bottom using `<div class="bar bar-tab">` in the surrounding div and then each link within the div uses `class="tab-item"`, but it doesn't always show properly (notice **Action** icon on far right):

I can pinch zoom to make it look like this:

Are there any suggestions for getting the proper behavior without pinching?
