Lines 1171 to 1177 in 93b33c5

	@at-root html h4#{&}-title {
	font-weight: bold;
	text-transform: uppercase;
	color: var( --clr-on-background ) !important;
	margin: 0;
	padding: 0;
	}

The above scss compiles to the following css in php-scss 1.x:

html h4self-header-title {
    font-weight: bold;
    text-transform: uppercase;
    color: var(--clr-on-background) !important;
    margin: 0;
    padding: 0
}

This PR adjusts the stylesheet to workaround the scss issue.

We're likely to push PHP-SCSS 2.0 later this week or early next. Let's wait unless very important
