Skill Cooldown buttons overlap Debuff buttons

[Alien13c]

The buttons that show the skill cooldowns (like Bestial Wrath) and the mob debuff buttons (like serpent sting) overlap when there gets to be a lot of skill cooldown buttons. This only happens when there are about 6 or more skill cooldowns. They seem to shift upwards and overlap the other buttons.

The buttons I'm referting to are the ones displayed toward the bottom of the HUD.
