display: Correctly add minor axis to snapping
There was an issue where the "minor" axis snapping would not be done if the "major" axis had a zero distance. This could be seen when e.g. moving a monitor on the right up/down slightly. In that case, no snapping to align the bottom/top edges were done unless you also moved the mouse sideways a bit.
