I have problem with override default background feature in web creator.

My snippet:

<template id="test" name="test"><section class="my_section"> <div class="custom_background"></div></section> </template>

When i set this element to data-selector to change default selector:

<div data-js='background' data-selector=".custom_background"

Menu with "background" not show on this snippet, it only works for classes in section (<div data-js='background' data-selector=".my_section")
