What is annoying though, is that because the WoW aura is still up, you won't see if DI procs AGAIN (refreshing the duration of the buff it gives you at the top of the screen) and actually resetting the CD. Unless you use a Power Aura to show when MB is off CD somewhere more visible on your screen but then, Blizzard could also just fix it by making it consuming the DI proc instead of using the MS glyph first
