[BUG] Can't remove style property on selected device

Hi, have a problem with removing style property on selected device (clearProperties: true). You can reproduce the problem on https://grapesjs.com/demo.html.

Steps:

1. Clean everything.
2. Drag custom code.
3. Add this sample code.

<div id="test">
  Test content
</div>
<style>
  #test {
  	color: red;
  }
  @media (max-width: 767px) {
    #test {
    	color: green;
    }
  }
  @media (max-width: 991px) {
    #test {
    	color: green;
    }
  }
</style>

4. Switch devices to tablet or mobile and select the component.
5. In the Typography style you can see that the COLOR property is YELLOW and there is NO clean icon.

I have X icon only on desktop device but on mobile or tablet is just yellow label.
