Leaflet : tiles didn't load : <p>I try to use the leaflet-map with polymer.
I add the leaflet-map tag inside my template, but when loading (and waiting) there is only one tile which is displayed (in the top left) with the original configuration (no leaflet-tilelayer, only set the latitude, longitude and zoom)</p>

<p>I switch to non-polymer version of leaflet, and try invalidateSize function, and there is always the same problem? I think i've missed something, but I don't know why.</p>

<p>Does anyone have any idea?
Thanks a lot</p>
