When changing password, only one line of Administrators message can be viewed without scrolling

Currently, only one line of an “Administrator’s message” can be viewed by the end user without scrolling down.

The message is added via:

iManager > Passwords > Password Policies > edit policy > Policy Summary (tab) > Password Change Message:

When the user views this dialog box when changing their password, only the first line of the administrator’s message is visible, and the user must scroll in order to see the whole message.
