Editor.setComponents auto generate unwanted css

In my use case I am constantly getting & setting the html/css inside the editor, and what I found is that it would end up duplicating the 'default' styles (see the * and body styles in the image above - they appear twice).

I managed to solve that by making sure to clear the css before I (re)set it - something like the following:

editor.CssComposer.getAll().reset();
editor.setComponents(components);
editor.setStyle(css);
