Cat form powershifting sometimes doesn't reapply bonuses after re-entering form

Occasionally upon shifting out and back into cat form rapidly, druids will lose part of their attack power bonus as well as their leader of the pack buff. This is obviously going to be very detrimental to feral DPS which is in a tenuous enough spot as it is.

Same with bear not applying Leader. I’m using cancelform macro. I haven’t been looking at my total HP, but if we’re seeing AP not applying, Heart Stamina may also be not applying.
