Font setting ignored

Hi,

I’ve read that you can change the font by customizing the CSS. I’ve added this:

.block-content {
 	--ls-font-family: "JetBrains Mono";
	font-size: 18px;
}

The font size is updated, however, the font is not. I’ve tried different fonts but none is working.

My version is 0.7.0.
