Fixed Background-repeat for multiple backgrounds breaks if saved in template and then in style properties

[CyberAP]

How to reproduce:

• Open any template that has some style property that supports background declaration. For example we open form.css and edit @button property.
• Add background-repeat: no-repeat, repeat; to that property and save template.
• Open your style property customization interface (in our case Buttons → Button). As you can see background-repeat declaration is not there. But it is actually stored in the property until you hit save.

This is fixed in that the "advanced" background-repeat rule isn't saved into the style property, as it's not something our system exposes. It will be pushed to extra.
