嵌入式推文在Mapbox弹出窗口中

我在弹出窗口中嵌入推文时遇到问题。我使用Mapbox GL JS和一个twitter小部件来设置弹出内容的样式。我将小部件放在click函数中,如下所示:



    // When a click event occurs on a feature in the places layer, open a popup at the
    // location of the feature, with description HTML from its properties.
    map.on('click', 'places', function (e) {
	
	//twitter widjet
	window.twttr = (function(d, s, id) {
	  var js, fjs = d.getElementsByTagName(s)[0],
		t = window.twttr || {};
	  if (d.getElementById(id)) return t;
	  js = d.createElement(s);
	  js.id = id;
	  js.src = "https://platform.twitter.com/widgets.js";
	  fjs.parentNode.insertBefore(js, fjs);

	  t._e = [];
	  t.ready = function(f) {
		t._e.push(f);
	  };

	  return t;
	}(document, "script", "twitter-wjs"));
        
		new mapboxgl.Popup()
            .setLngLat(e.features[0].geometry.coordinates)
            .setHTML('<h3>' + e.features[0].properties.title + '</h3><p>' + e.features[0].properties.description + '</p>')
            .addTo(map);
    });
&#13;
&#13;
&#13;

使用Twitter的嵌入链接将推文本身硬编码到Geojson的描述部分:

&#13;
&#13;
map.on('load', function () {


    map.addLayer({
        "id": "places",
        "type": "symbol",
        "source": {
            "type": "geojson",
            "data": {
                "type": "FeatureCollection",
                "features": [{
                    "type": "Feature",
                    "geometry": {
					    "type": "Point",
                        "coordinates": [-6.2285,53.3475]
                    },
                    "properties": {
                        "title": "3arena",
                        "icon": "stadium",
						"description": "<blockquote class='twitter-tweet' data-lang='en'><p lang='en' dir='ltr'>.<a /*TWEET INFO*/ </a></blockquote>"
                    }
                }]
            }
        },
        "layout": {
            "icon-image": "{icon}-15",
			"icon-size": 2,
			"icon-allow-overlap": true
        }
    });
});

tweet popup只运行一次,但在此之后无法设置弹出窗口样式,即使click功能继续有效。任何有关此事的帮助将不胜感激。这是一个有效的例子:
