pre-grid size of application window is lost, when restoring an application in maximized mode and then moving to left/right edge using <ctrl>+<super> keybind

3) What you expected to happen:

upon restoring a maximized application, and then moving the application window to a grid on the left or right part of the screen using the <ctrl>+<super>+left/right keybinding, i should be able to restore the window to a pre-grid size if dragged away from the gridded position.

4) What happened instead:

window collapses to minimal size after dragging away application window from gridded position. this happens with almost all applications. i have also tried enabling "snap windows back to original size" from the CCSM grid-plugin settings, with no success.

thanks

i'v attached a screencast video of the problem.

here's an attachment of screenshot, step by step, using chromium as example:

1) start application in maximized mode.

2) move window to a grid on the left side of the screen using <ctrl>+<super>+left

3) drag window away using cursor from gridded postion, window collapses instead of retaining pre-gridded size.

Status changed to 'Confirmed' because the bug affects multiple users.

I am also affected by this bug and it is especially annoying when using eclipse IDE, which "collapses" to a tiny barely visible line (see attachment).
This bug is besides ubuntu 14.04.x also present in 14.10 and 15.04! I asked about this beaviour in ubuntu ask (https://askubuntu.com/questions/569574/ubuntu-eclipse-window-disappears) and there is one more person affected by this bug

still present in 16.04...
