/**
 * Safari 10.1 supports modules, but does not support the `nomodule` attribute - it will
 * load <script nomodule> anyway. This snippet solve this problem, but only for script
 * tags that load external code, e.g.: <script nomodule src="nomodule.js"></script>
 *
 * Again: this will **not** prevent inline script, e.g.:
 * <script nomodule>alert('no modules');</script>.
 *
 * This workaround is possible because Safari supports the non-standard 'beforeload' event.
 * This allows us to trap the module and nomodule load.
