Netbeans after interpolation in a selector with a reference to the parent, the SCSS syntax is not highlighted. How to fix? Or how to set up the SCSS Support plugin?

Question

NetBeans

There is this code:

.dis-thing {
    @for $i from 0 through 4 {
        &__text_lvl_#{$i+1} {
            font-size: 26px - 2 * $i;
        }
    }
}

SCSS syntax is not highlighted after it. It's like the plugin is disabled. If I replace & with .dis-thing, then everything works. Here is a screenshot:

How to fix it?
I tried to download another plugin (not native) for SCSS. This one: plugins.netbeans.org/plugin/34929/scss-support
There is no such problem here. However, there is another. If I open the brackets {} and put the cursor between them and press Enter, then my selector automatically moves 1 tab to the right. Here are the screenshots:
