-------------------------+---------------------------------------
 The `WP_Style_Engine` class has a method get_classnames that builds
 classnames.

 It loops over an array to add each classname.


 There should be a `continue` in the loop after adding the default
 classname.

 **Why?**

 Because we've added the first classname by virtue of testing for `true`.
 The following tests all expect a string: `get_slug_from_preset_value` only
 works on a string, not a boolean.
