CSS grid layout broken

Hi! Thank you for the great work on this plugin!

The plugin broke a CSS grid layout. When I turn on CSS minification or combine this code:

#publicacoes {
	display: grid;
	grid-column-gap: 45px;
	grid-row-gap: 45px;

	grid-template-columns: calc( 50% - 22px ) calc( 50% - 22px );

	grid-auto-rows: minmax(min-content, max-content);
	padding-top: 40px;
}

Change to this:

#publicacoes {
	display: grid;
	grid-column-gap: 45px;
	grid-row-gap: 45px;

	grid-template-columns: calc( 50% - 22px ); /* second column gone */

	grid-auto-rows: minmax(min-content, max-content);
	padding-top: 40px;
}

Any idea for workaround?
