Street labels in Mapbox Tile Layer too small
<p>I have the following Leaflet map: <a href="https://jsfiddle.net/zq02pnpg/1/" rel="noreferrer">JSFiddle link</a></p>

<pre class="lang-html prettyprint-override"><code>&lt;div id="mapid" style="height: 300px;"&gt;&lt;/div&gt;

&lt;script&gt;
  var mapboxTiles = L.tileLayer(mapBoxUrl, {
    attribution: attributionText
  });

  var map = L.map('mapid')
    .addLayer(mapboxTiles)
    .setView([42.888284, -78.877222], 16);

&lt;/script&gt;
</code></pre>

<p>The font size for the street labels is very small, to the point of being unreadable, and when you zoom in, the font size gets smaller.  Is there a way to control the font size?</p>
