Sequencer- Nested enum properties in structs don't show enum options for sequencer animation

Find or create a blueprinttype UStruct with a UEnum inside it tagged with 'interp' to be animatable in Sequencer. 

Add a variable of the ustruct type to a blueprint actor.

Create a sequence with a spawnable of that actor inside it.

Add the track for the UEnum subproperty.

Notice that no options for the enum show up. Contrast this with another enum property that isn't inside a struct.
