NOTE: I am aware that IE does not support client-side projection, but I don't believe client-side projection should even be required in this instance...
I am using a Basemap with wkid of 2193, and I am able to draw Graphics in 2193 to Graphics Layers on the view. However: if I try to add Feature Layers with a source in 2193 to the map I get [esri.views.2d.layers.FeatureLayerView2D] [feature-store:unsupported-query]: projection not supported error... Everything (Basemap, Graphics, Feature Layers) is in 2193, why is the API even trying to project it?
Has anyone noticed this before? Any ideas?
Here is a codepen demonstrating the issue: https://codepen.io/stacy-rendall/embed/dyMzdyX - as you can see, the 2193 graphic draws fine in IE11, but the 2193 Feature Layer does not... Editable version of the Pen here: https://codepen.io/stacy-rendall/pen/dyMzdyX (note that it cannot be edited in IE)
