Description

If a Component/ variable is given a custom category in code, using the HideCategories specifer inside the UCLASS macro does not hide the category.

Steps to Reproduce

1. Open UE4Editor (code project)
2. Add code to project based on Actor (MyActor)
3. In the MyActor header file add the following:

UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = TestHiddenCategory)
float number;

4. Inside the UCLASS macro add the following

HideCategories = (Actor, Render, TestHiddenCategory)

5. Compile
6. Make a blueprint based on MyActor (MyActorBP)
7. Add instance of MyActorBP to the level

Result:
Actor and Rendering categories are missing (hidden) but TestHiddenCategory is still visible.
