This worked for me:
//Background
local bg = fe.add_image("bg_base.png", 0, 0, flw, flh);
local bg_shrink_cfg = {
when = When.StartLayout,
when = Transition.ToNewList,
property = "scale",
start = 1.4,
end = 1.0,
time = 1000
tween = Tween.Quad,
}
animation.add( PropertyAnimation( bg, bg_shrink_cfg ) );
Maybe cant be "0" , try "-0.001" to "1.0"
