On the server, @slideSidebarPadding always resolved to 'expanded' because slideSidebarOver did not emit true
This resulted in the SSR HTML leaving space for the expanded sidebar.
Also got rid of the sliding animation as it would always play, even when replacing SSR HTML where the sidebar was already visible.
