Open a map in Japan. Pan to the US. You won't see features.
Cause is due to wrap-around at dateline, and more specifically, the display bounds does not wrap but the transform from EPSG 4326 does. Here is some debugging data:
This is correct:
WorldDisplay?: [Mercator Transform [ radius: 325.94932345220167]
Affine Transform [a: 1 b: 0c: 0 d: 1 e: 1024 f: -1024]
Affine Transform [a: 1 b: 0c: 0 d: -1 e: 0 f: 0]
WorldToView?: [Mercator Transform [ radius: 325.94932345220167]
Affine Transform [a: 1 b: 0c: 0 d: 1 e: 1024 f: -1024]
Affine Transform [a: 1 b: 0c: 0 d: -1 e: 0 f: 0]
Affine Transform [a: 1 b: 0c: 0 d: 1 e: -164.5 f: -608.5]]"

Bounds

This is wrong:
WorldDisplay?: [Mercator Transform [ radius: 325.94932345220167]
Affine Transform [a: 1 b: 0c: 0 d: 1e: 1024 f: -1024]
Affine Transform [a: 1 b: 0c: 0 d: -1e: 0 f: 0]]
WorldView?: [Mercator Transform [ radius: 325.94932345220167]
Affine Transform [a: 1 b: 0c: 0 d: 1 e: 1024 f: -1024]
Affine Transform [a: 1 b: 0c: 0 d: -1 e: 0 f: 0]
Affine Transform [a: 1 b: 0c: 0 d: 1 e: -2204.5 f: -625.5]
