How to reproduce.
1. Log in to JIRA and begin to create a new dashboard by clicking "Dashboards -> Create Dashboard",
2. Under the "Viewers" section select "Group", then in the drop-down to the right where a list of all groups is displayed see that full group names are not displayed due to the width being too small.
Note: Our group names are all prefixed with about 20 characters, this means every row only displays the prefix. Hovering over the group name also does not show a tool-tip which would be a workaround.
Expected behavior:
The full group name should be visible and the drop-down should expand to display all the options.
