The timestamp previously added, forces the browser to ignore its own cache and thus it doesn't transmit the `If-None-Match` header. We then re-calculate the the CSS possibly for no reason. If there is a re-calculation indeed required it should be still done now since the ETag transmitted by the browser is outdated. refs #4340
