if the following layout is in use:

AB=1000 BD=200
AB
AD

And A has focus, if i toggle the BD containers by moving leftx2 everything works as expected and BD=200 is true. Or if B is active and i toggle D by moving upx2, everything works BD=200 is true.

but

If I hide D by moving B up, then focus A move it leftx2 then focusing B and moving it up, now BD=200 is false (its the default, 50%). So that is the issue here, BD should be 200.
