Question [Q] Dock position unmoved after hiding softkey

Phone: Sony Xperia Z L36H C6602
System: Official 4.4.2 KK 10.5.A.0.230 (Rooted with towelroot)

hi guy,

i just notice today that, in 4.4 (firmware .230)
when you hide / resize the softkey with app such as GMD Auto Hide Softkey or Xposed module
the app dock on the home screen stays at the same position / height
instead of moving down with the hidden / height reduced softkey, like in the previous .101 firmware

hidind softkey between 4.3 & 4.4

is there a way to prevent / stop it from "stuck" in one place?

also, is there no more dock stage starting from this firmware?
or is there a way to enable it?
i really miss the old 4.3 GUI
