Widget classes when custom widget class is namespaced

[rogerlos]

Widgets output from a namespaced class have a class added to the before_widget argument in a way which is potentially confusing and messy to work with.

The before_widget value within the arguments array sent to the widget() method within WP_Widget looks something like this when using a namespaced custom widget class:

<aside class="widget \myplugin\My_Widget" id="mywidgetname_widget-1">'

Given my understanding of WP's "normal" escaping of attributes, I would have expected myplugin-My_Widget, mywidgetname myplugin-My_Widget or maybe mypluginMy_Widget.

I believe that technically the two escape characters make the WP output the equivalent to the latter, but it's a bit messy and potentially confusing to folks looking to style the output, or find the aside using JS.

@rogerlos thanks for the ticket! Can you share the code you are using to register the widget? My local tests are not getting the same results.
