Array of structs does not animate sub properties correctly in Sequencer.

Support for animating arrays of structs should either be disabled, or supported.

1. Create a C++ class in a project inheriting from Actor
2. Create a UStruct with two float UProperties that are marked as Interp and BlueprintReadWrite.
3. Create two UProperties on the C++ class, a single instance of the struct, and a TArray of the struct, make them both Interp and BlueprintReadWrite
4. Add the actor to a level sequence, and add entries in to the struct array.
5. Add tracks to the actor for the single struct, and the array of structs. Notice that when adding elements from the array, you cannot select the individual properties from the struct.

RESULT

Structs in arrays cannot have their individual properties animated.
