Do not set ReferrerUrl on routeChangeStart

[carolineBda]

This param is used to determine how someone got to the website and not for internal navigation : https://developer.matomo.org/api-reference/tracking-api#optional-user-info

As they say here we only need to call setCustomUrl and setDocumentTitle before trackPageView

So we need to remove this bit

Il parle aussi dans la section Updating the referrer un peu plus bas que l'on peut mettre à jour le referrer également. Par contre ça manque d'information de pourquoi je voudrais indiquer un referrer 🤔

D'ailleurs dans l'exemple plus loin (Measuring Single-Page Apps: Complete Example), il set un referrerUrl à la current page :

var currentUrl = location.href;
window.addEventListener('hashchange', function() {
    _paq.push(['setReferrerUrl', currentUrl]); <------------------ ICI
     currentUrl = '/' + window.location.hash.substr(1);
    _paq.push(['setCustomUrl', currentUrl]);
    _paq.push(['setDocumentTitle', 'My New Title']);

    // remove all previously assigned custom variables, requires Matomo (formerly Piwik) 3.0.2
    _paq.push(['deleteCustomVariables', 'page']);
    _paq.push(['AbTesting::create', {
       name: 'theExperimentName',
       includedTargets: [{"attribute":"url","type":"starts_with","value":"http:\/\/www.example.org","inverted":"0"}],
       excludedTargets: [],
       variations: [
          {
             name: 'original',
             activate: function (event) {
                // usually nothing needs to be done here
             }
          },
          {
             name: 'blue',
             activate: function(event) {
                // eg $('#btn').attr('style', 'color: ' + this.name + ';');
             }
          }
       ]
    }]);
    _paq.push(['trackPageView']);

    // make Matomo aware of newly added content
    var content = document.getElementById('content');
    _paq.push(['MediaAnalytics::scanForMedia', content]);
    _paq.push(['FormAnalytics::scanForForms', content]);
    _paq.push(['trackContentImpressionsWithinNode', content]);
    _paq.push(['enableLinkTracking']);
});
