Sorry to be that guy, but if you are using an open source library and it adds hats that you're unhappy with that means you did not check the library you are including.

Maybe not looking at code one includes in a product has become much too common practise, but if some library for a button (funny I never felt the need to use one) includes special stylings on special days and you included it, that is on you. Sure it would have been nice of them to point this out if they didn't, but after all you are taking someone elses code for a button so you should know what it does.
