SUMMARY
When I use meta + down arrow on Firefox, to snap my window to the bottom of my secondary, vertical monitor, it get snapped slightly off-screen, around 50 pixels to the right.
Monitor is 1440p vertical (1440 x 2560)
Only seems to happen with Firefox, and only when the window is not already snapped.
If the Firefox window is already snapped, I can use meta + left and then meta + right to fix the issue.
Only happens on bottom half of the screen, snapping to top is fine

STEPS TO REPRODUCE
1. Open Firefox with a vertical monitor
2. Snap using Meta + Down
3. Observe that the minimize / maximize / close buttons are now off screen
