[BUG] CyLeaflet: Updating tile layer causes map to be initially blue before pan/zoom

[Farkites]

I've been doing some tests and I've seen that if the browser inspector is open on the side the tiles update works as expected the first 2 times (not including the initial load). If the browser inspector is open on a different window or is not opened at all I can see it failing on the first update. I haven't been able to reproduce the first behaviour by changing the window size.

In the Network traffic I see that for each update of updateLeafBounds it first tries to load tiles that are wrong (default position in the map) and then loads the correct tiles according to the latitude and longitude, cancelling the first tiles. The defect we see here is because leaflet is not requesting the correct tiles so either the wrong tiles are loaded (for CARTO tiles) or the request for the tiles fails (for OSM tiles).
