flickering in Firefox

[teenriot]

The demo is flickering between colored and grayscale in Firefox 56.0 (32-Bit) (tested with Windows 7)

Even when using fadeAnimation: false as suggested in the README?

I've added fadeAnimation: false as suggested, but I also have the same issue as mentioned above. var map = L.map('map', { center: [55.958, 11.635], zoom: 7, minZoom: 7, maxZoom: 15, fadeAnimation: false });
