Setting a drop-down field as "Required" behaviour broken

• Jira Version 7.3.1
• Scriptrunner Version: 4.3.18

Setting a drop-down field as “Required” in a behaviour, will result in unexpected outcome. The field that has been set as “Required” will be mandatory, you will not be able to update without adding data to that field. The issue is a visual one. When a field is required, then a red asterisk should be displayed against the label for that field. Instead, for drop-down fields, that red asterisk is displayed against the attachments field label.
