Selecting different options in modal breaks select box

(See jdiefenbaugh/beat.web#13)

When adding experiments to a report, you are asked to select which report to try to add the experiments to. The first time you select any available report, the report name correctly shows as the "selected" value. However, after a few times of choosing different reports, the selected report name is pushed to the far right, and you can't read it.

Just by playing around in the browser's inspect mode, I was able to fix this issue by changing the raw HTML. Changing the HTML element that contains the selected report name from a div to a span corrects this - I'm guessing it's because divs are not inline by default, while spans are.
