Tiles won't load while dragging map

When dragging any Leaflet-map out of the "preloaded tile-zone", missing tiles will not load until user lifts finger (on iPhone or iPad, currently iOS 14.5.1, using Safari).

Expected behavior Missing tiles load while user is still dragging the map (works in other configurations or Google Maps or newer versions of OpenLayers)

Current behavior they don't 8o)

Environment

• Leaflet version: 1.7.1 (and earlier)
• Browser (with version): Safari
• OS/Platform (with version): iOS 14.5.1 (and earlier)

Additional context none

Minimal example reproducing the issue Can be reproduced with any Leaflet-map, just drag the map far enough until new tiles need to be fetched
