participants page edit icon and help icon misaligned.

Test pre-requisites A course with some students enrolled. Important - A manager for the course. Test steps Log in as the manager (this won't work with an administrator - MDL-37026 ) Go to the participants page. There should be an edit icon next to the heading 'All participants' in the middle of the page. Make sure that it is the round edit icon (not a pencil) and that it is an appropriate size. At the bottom of the page there should be a help icon next to the label 'With selected users...'. Ensure that there is some padding between the help icon and the text. Change the 'current role' select box to 'teacher' or 'student'. Check that the edit icon in the same location as step 3 is the same.
