Additional Information

The issue is that the geometry is not normalized. A polygon that crosses the dateline must be defined with two rings, one for each side of the dateline, to be considered a normalized geometry. Each ring must start and end with the same vertex. The client-side FeatureLayer expects the geometries of graphics added via the source property to already be normalized. This maintains optimal performance in the case of large client-side layers. This can be done for GraphicsLayer because the cost of normalizing one or just a few feature(s) is relatively low. However, a layer created with many features can really slow down the startup of the layer. Create normal geometries for the rendering to work, or add features to the FeatureLayer with applyEdits, which normalizes all input geometries on behalf of the user.

Workaround

Create the layer with simple, normalized geometries. For example, if a geometry spans the dateline, it should be normalized to have two rings.
Use applyEdits which does the normalization for the user. For example, refer to the following link: https://codepen.io/ycabon/pen/zYedvOv?editors=0010.
