Question the touch actor behavior does not work when the interpolating the width and heigh

hey guys
I m not sure if this a bug or intrinsic property of GS, I used a rule to interpolate the width and the height of an actor ( to give some animated effect) I noticed when the actor is interpolating its dimension, it will not react to touching other actors behavior. I attached a file explaining what I mean, if you go to the green actor and turned off the distort rule then it will react to the bullet that been shot at it, other wise it will not
is there any way to go around this ?
