Click on XP bar doesn't move character

Ok, the title basically describes the problem. When you click the very bottom of the screen you don't move in that direction.

Why is that a problem? Well when I'm frantically try to get away from a fight because I'm at low health and the way back happens to be downwards that often leads to a moment of not moving before I click somewhere else. You usually don;t realize what happened but it sometimes becomes a problem when you have to get away in a certain direction.

You don't need to click on the XP bar for anything else, so nothing in teh way of making that a normal "movement area".
The health and mana bubbles are already working that way. Clicking on them does cause you to move.

Edit: I also noticed the same problem with buff/debuff icon in the top left corner. Might also sometimes cause problem if you happen to click exactly there to move away in a tight situation.
