Heat Beam runes remove off balance only

[EatThisShoe]

When you get a physical effect, say stun, and also the cross tier effect, using a heat beam rune has a chance to remove the cross tier effect instead of the actual debuff. I'm not 100% sure this is a bug, but I'm assuming it is since Wild Infusions always remove both the physical effect and the cross tier. I haven't tested frozen spear runes.
