super+left shortcut not usable for switching workspace

[Dolf Schimmel (Freeaqingme)]

Hi.

Under settings => keyboard => shortcuts => navigation I changed the value of 'move to workspace left' from ctrl+alt+left to super+left (winkey + left). I did the same for moving to other workspaces using the respective arrow keys.

Incentive: To me, it's easier switching to other workspaces.

Expected behavior:
* Whenever I press winkey+left I move to the workspace left of the current one.
* Whenever I press winkey+right I move to the workspace right of the current one.
* Whenever I press winkey+down I move to the workspace below the current one.

Problem:
If I have an active window (a window I clicked on prior to performing the shortcut) like firefox, and I perform a winkey+right I do not switch workspace. Instead the window snaps to the right side of the screen.

Other observations:
* This only happens if I have an 'active' window. If I first click on my background this behavior is not observed.
* If I have a dialogue activated like the settings screen, the behavior is not observed and the expected behavior is given.
* I updated my system one or two days ago and suddenly my shortcut settings had been reset to what I presume are their defaults.
