As a matter of fact, while this is known for Hunter and Warlock already, Titans also have that problem, I did observe that it only affects the parts of armor that are affected by cloth physics from what I have seen, so the Cape of a hunter, the Lower portion of a Warlocks robes and the Front and Back pieces of cloth on a Titan mark, the only thing different on the Titan one is that it is not as noticeable because the cloth does color while the gold parts still don't.
