<p>it is still broken in iPhone7 with latest Safari and iOS13.1. The tile is not requested, instead a tile is requested that isn't visible at all (only 3 tiles, all of the same column, are requested). This is the whole tile-container:</p>
<p><code><div class="leaflet-tile-container leaflet-zoom-animated" style="z-index: 19; transform: translate3d(0px, 0px, 0px) scale(1);"><img alt="" role="presentation" src="https://c.tile.openstreetmap.org/17/74534/38466.png" class="leaflet-tile leaflet-tile-loaded" style="width: 256px; height: 256px; transform: translate3d(-173px, 171px, 0px); opacity: 1;"><img alt="" role="presentation" src="https://b.tile.openstreetmap.org/17/74534/38465.png" class="leaflet-tile leaflet-tile-loaded" style="width: 256px; height: 256px; transform: translate3d(-173px, -85px, 0px); opacity: 1;"><img alt="" role="presentation" src="https://a.tile.openstreetmap.org/17/74534/38467.png" class="leaflet-tile leaflet-tile-loaded" style="width: 256px; height: 256px; transform: translate3d(-173px, 427px, 0px); opacity: 1;"></div></code></p>
