Steps to reproduce:

• Go to Administration->General->Trigger displaying options
• Change severities name ( maxlength = 32)
• Save the changes
• Go to any dashboard and open widget edit or create modal form
• Choose any widget type where severity filtering is present (e.g. Problems, Problem hosts, Problem by severity, Top triggers (master only))
• Check severities

Result: Long custom severity labels don't fit widget form size.

Expected: severity labels should fit form size.

Note: the issue can possibly appear using some languages where long labels are present.
