11327	Widgets might get null bytes in their CSS class	qualipsoft	azaozz	"When register_sidebar_widget is called with a lambda/create_function as output_callback and no/empty classname, the widget's CSS class will contain ""\0lamba_123"" (\0 being the null character and 123 being the actual assigned lamba id).

This bug was introduced in 2.3 by #4910 (In [6098]).

The simple fix might be to left-trim null bytes from the classname (this would fix the case for lambda's, and maybe other cases I'm not aware of)"	defect (bug)	closed	normal		Widgets	2.3	normal	wontfix	widgets css class has-patch
