Bug or Feature? UISprite and UIFilledSprite the same?

[ENAY]

Something just caught me out. Ok, so I was going through my objects using GetComponentsInChildren<UIFilledSprite> and I decided to add 2 UISprites in the intention that I could simply get at them quickly with

GetComponentsInChildren<UISprite>()[0]

etc.

Until I found out that no matter which I search for, both types of sprites are in the same list. Is this normal behaviour?
I am thinking that this is a feature.

That's polymorphism for you. UIFilledSprite extends UISprite, ergo, all UIFilledSprites are also UISprites.


If all UISprites are listed as UIFilledSprites that's weird though.
