I don't think there's any way to change the WebView's cache size; potentially we could make sure that Leaflet doesn't discard tiles as quickly as it does, but I'm a bit unsure how.

The 'reuseTiles' option on TileLayer _might_ or might not help (or it might just more actively recycle the tiles :)

It's issues like this that make me want to go native for tiles.

Overly complicated for now, requires some exploration. tabling for now.

[Closing as "WONTFIX" to get rid of the deprecated "LATER" resolution]
