DialogFragment over DialogFragment produces spawn with no background animation

Question

Good evening. A fast question.

i have seen that showing a not-fullscreen dialogfragment over activity or fragment, animates normally. but when dialogfragment is showing over other dialogfragment, it animates the view BUT the dimmed background is not animating..its just appears.

Any reason why? also any workaround?

example: Open a fullscreen dialogfragment and then open a non-fullscreen dialogfragment. You will notice that the "semitransparent" dim background is never animating.

If the fullscreen dialogfragment, were fragment(or activity), it would work fine
