VS fails to compile when USTRUCT is referenced as BlueprintReadWrite or BlueprintReadOnly

Defining a FBoneReference variable as BlueprintReadWrite or BlueprintReadOnly in the UPROPERTY macro fails to compile in 4.17. The error message provided by VS states:

LogCompile: Error: Type 'FTestStruct' is not supported by blueprint. MyActor.Rando

This is likely caused by FBoneReference's USTRUCT not including the BlueprintType specifier

Regression:
Yes - Code provided in repro steps does compile successfully in 4.16.3 binary

Workarounds:

• Adding BlueprintType to FBoneReference's USTRUCT macro allows repro code to compile
• Creating a wrapper struct that is BlueprintType with a FBoneReference variable will compile if FBoneReference FingerTipBone; is replaced with FWrapperStruct WrapperVar; in the repro steps
• Removing BluerpintReadWrite from the UPROPERTY macro allows VS to compile

1. Open UE4 Editor (any project)
2. Add code to project based on Actor (MyActor)
3. Add the following struct above the UCLASS macro

   USTRUCT()
   struct FTestStruct
   {
        GENERATED_BODY()
        float someNum;
   };
   

4. Add the following to the body of the class

   UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = test)
   FTestStruct Rando;
   

5. Compile

Result:
Compile fails stating that FTestStruct is not supported by blueprints

Expected:
VS compiles successfully with exposed FBoneReference variable
