If you have more than 5 buffs on your character, they go to a second row in the upper left of the screen. However, you can't mouse over the ones in the second row to bring up information. I did check with default client.
This is a problem because the first row can get filled with things like your realm or visitor, and then "drink and be merry" gets pushed to the second row. You need to mouse over to see which drinks you have ready to apply to food.
