I am struggling for some time now to get the leaflet map loaded properly within Polymer 2. I have searched various threads in SO: this, Github: this, this and several other posts, unfortunately still could not fix the issue. Tested in both Chrome and Firefox.

My map renders like this:

enter image description here Code

<style include="shared-styles publish-project-styles">
:host {
display: block;
padding: 20px;
}
#mapContainer{
    width: 100%; height: 400px; border: 1px solid #0A569D;
}

.leaflet-container{
    width: 100%; height: 400px; border: 1px solid #0A569D;
}

<td  id="leftContainer" width="50%" style="padding: 15px;">
 <div id="mapContainer"></div>
 <!-- <canvas id="mapContainer" style="width: 400px; height: 400px; border: 1px solid #0A569D;"></canvas> --></td>

connectedCallback() {
super.connectedCallback();          
let leafmap = L.map(this.$.mapContainer).setView([48.84, 2.3], 5);
L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
            maxZoom: 18
        }).addTo(leafmap);
leafmap.invalidateSize();
}

I did try with inline CSS, putting JS in connectedcallback(), putting CSS in parent element etc. I also consoled this.$.mapContainer.innerText which is blank.

I am assuming, there is some CSS problem given the posts that I read. But not sure.

Can someone could help in this regard?

Was unsure, if I should delete this post or not as I have posted the same question in SO. I assume, if someone is searching for this in GIS SO, they can find the answer here. So not deleting the post.
