	--available-space: calc(100vh - 54px - 20px);
	--shortened-post-height: calc((var(--available-space) * var(--xkit-shorten-posts-max-height)) - 20px);
	--expand-button-total-height: calc(1rem + (var(--post-header-vertical-padding) * 2));

This code calculated the available height for posts based on the old layout with the header and is now incorrect in both the desktop layout (which has no header) and the mobile layout (which has a 44px header).
