Removing title on widget doesn't modify in-widget-title span

[chrisbliss18]

In the widget editor, widgets with titles have this title shown in the widget editor container title. For example:

Text: Sample Widget

When a widget is first modified and saved, adding a title will cause this widget editor container title to update via JS to reflect the title update. Subsequent modifications of the title will also be reflected. However, if the title is removed, the previous title will remain.

Looking at the code shows that the in-widget-title span that holds this widget editor container title is only updated if the title value is not empty. This is easily tested by adding a Text widget, giving it a title, clicking Save, confirming that the title is reflected in the container, removing the title, and clicking Save again.

The supplied patch modifies the JS that handles this process and causes it to always update the in-widget-title span, even when the title entry is empty or missing.

I don't know if something went wrong when I manually applied this to the dev.js file but I couldn't get it work :-(

Curious. What system and browser are you using? Maybe it is a JS issue.

I'll do more testing on it.

Patch refreshed. Needs compressing.
