#19925: Empty widget title in admin not handled properly
----------------------------+-----------------------

     Type:  defect (bug)    |     Status:  new
 Priority:  normal          |  Milestone:  3.4
Component:  Administration  |    Version:  3.3.1
 Severity:  normal          |   Keywords:  has-patch
----------------------------+-----------------------
 '''Steps to reproduce:'''
 1. Add a widget
 1. Enter a title and save
 1. Clear the title and save
 1. The title in the widget handle will stay set to the original title
 value

 Line 252 of `wp-admin/js/widgets.dev.js` checks whether `title.val()` is a
 valid value, but this will also reject empty strings. Attached patch
 checks rejects for undefined values and clears the widget's handle title
 if the string is just empty.
