disallowHtmlText failing on bracket in inline JS block

[gvn]

The following pug code causes the disallowHtmlText rule to fail.

script.
  (function () {
    var _dntStatus = navigator.doNotTrack || navigator.msDoNotTrack;
    var fxMatch = navigator.userAgent.match(/Firefox\/(\d+)/);
    var ie10Match = navigator.userAgent.match(/MSIE 10/i);
    var w8Match = navigator.appVersion.match(/Windows NT 6.2/);

    if (fxMatch && Number(fxMatch[1]) < 32) {
      _dntStatus = 'Unspecified';
    } else if (ie10Match && w8Match) {
      _dntStatus = 'Unspecified';
    } else {
      _dntStatus = { '0': 'Disabled', '1': 'Enabled' }[_dntStatus] || 'Unspecified';
    }

    if (_dntStatus !== 'Enabled'){
      (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
      (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),

HTML text must not be used

I believe this is because of the < character being mistaken for HTML.
