Long entries in the Potential Recipients or Potential Groups boxes push the list boxes outside of the display area.

Additionally, once a student (who is in a group with a very long name, or multiple groups with long names) is added to the Selected Recipients box, the Potential Recipients, Potential Groups, and Role Filter drop-down menu can be entirely inaccessible.

Steps to reproduce:
Create a group "My Very Long Group Name Abracadabra"
Create another group "Her Very Long Group Name Bedrock"
Add a student to each group. Add one of the students to BOTH groups.
Go into Quickmail > Compose new email

• note how the Potential Recipients box is truncated
  Select the student in both groups and click "Add" button.
• note how the Potential Recipients box is entirely gone and the Add/Remove buttons are almost gone.

The display area should expand to accommodate the longer names.
At the least, the boxes and drop-down menu should be aligned left so they're still accessible in the display area.
