window movement between splits broken

[litoj]

Description:
when I move a window (x) from Vsplit to a window (s) in Hsplit, it goes to the upper layout in reverse order and the window size breaks into ratio 2(w1):3(x):4(s) instead of being 1:1:1

try with layout like:
H[w1,V[H[s],x]]; swaymsg move up -> H[w1,x,s]

The after this action the layout should be:
H[w1,V[H[s,x]]]

with ratio 2(w1):1(s):1(x)

Unfortunately I don't understand at all how something so weird could be happening, but I find it very surprising noone else finds this annoying.
