Screenshot displaying the behavior

SUMMARY
When tiling the System Settings left the application uses more than 50% of the screen, thus overlapping with a different application tiled to the right side of the screen. When inverted, System Settings being tiled right, it runs of the side of the screen. The same can be observed with the Info Center application

STEPS TO REPRODUCE
1. Open a random application (e.g Firefox) and tile it to the right (using Meta+Right arrow)
2. Open System settings and tile it to the left (using Meta+Left arrow)

OBSERVED RESULT
System Settings overlaps the application tiled on the right side of the screen

EXPECTED RESULT
System Settings resizes to use 50% of the screen instead of overlapping.
