<p>In <a href="https://github.com/openstreetmap/openstreetmap-website/pull/5416#discussion_r1891385635">app/assets/javascripts/leaflet.share.js</a>:</p>
<pre style='color:#555'>> @@ -411,34 +416,20 @@ L.OSM.share = function (options) {
       $("#mapnik_image_width").text(mapWidth);
       $("#mapnik_image_height").text(mapHeight);
 
-      const layerId = map.getMapBaseLayerId();
-      const layerKeys = new Map([
-        ["mapnik", "standard"],
-        ["cyclemap", "cycle_map"],
-        ["transportmap", "transport_map"]
-      ]);
+      const canDownloadImage = layer && layer.options.canDownloadImage;
</pre>
<p dir="auto">This doesn't guarantee a boolean valued result - specifically if the <code class="notranslate">canDownloadImage</code> key is missing then the result is <code class="notranslate">undefined</code> not <code class="notranslate">false</code> and at least in Firefox calling <code class="notranslate">toggle(undefined)</code> toggles the current visibility instead of always hiding the element though I don't think the behaviour is defined at all by jQuery.</p>
