SearchBuilder in Buttons not working with Bootstrap 3

Link to test case:

Description of problem:
Without Bootstrap 3, it works fine. I click on the button and can configure the SearchBuilder.
With Bootstrap 3, the SearchBuilder dialog is too small and I cannot add conditions, because the dialog immediately closes.

Would appreciate a workaround, if there is one.

Thanks!
