Title: Fixes #4002 Multiple responsive utility classes

Solves unexpected behaviours when more than one responsive utility classes is assigned to an element.

As required added the tests into the css-tests.html file. Added the default working tests (single classes) and the combined classes examples that had unexpected behaviours.
