Because the HTML parser stopped, all network traffic also stopped (because no other HTML tags were parsed to initiate HTTP requests). Before these were widely supported, developers could load scripts asynchronously using a variety of techniques (i.e., In late 2015, the median was 10 synchronous scripts and 2 asynchronous scripts.
