Please describe the problem:
I am intensively using hotkeys to toggle window maximization. I don't just use full window maximazition toggle but also the vertical and horizontal toggelings. Since gnome 2.20 only the full window maximization toggle is functioning correctly, horizontal/vertical max. toggle only are screwed up after one did a single full window max. toggle. 

Ahh and this is a regression bug, it was working all fine in 2.18 and many version below that.


Steps to reproduce:
To reproduce, assign keys to toggle window maximzation, I use:

<apple>+M -> maximization toggle
<apple>+H -> horizontal maximization toggle
<apple>+V -> vertical maximization toggle

1. Now open a small window (it must be a freshly opened one)
2. press <apple>+M twice - the window will be fully maximized and restored to what it was before
3. press <apple>+V once - the window will again be maximized but not only vertically but fully - ahh yes and the same happens with <apple>+H
4. press <apple>+V again - the window will now not restore to the previous size/location but remains horizontally maximized (with <apple>+H it would now be vertically maximized)


Actual results:
the bug occurs

Expected results:
the bug not to occur

Does this happen every time?
yes
