If using a non-global basemap (i.e. a basemap in 2193) Firefox runs into WebGL memory issues - not quite every time, but pretty consistently. I have made two example CodePens with the same set of feature layers, only difference is basemap and coordinates of the initial extent:
Both examples work OK on Chrome and even legacy Edge. Issue is replicated in both JS API 4.16 and 4.17 (haven't tested other versions).
Am I doing something crazy here?
