Sorting filtered Product Backlog

There are cases where sorting is ambiguous.

Given Three Stories stoa, stob and sto, tagged with the same Theme, when a filter is applied and the downmost is dragged up and dropped between the other two, it is unclear, whether to drop above the lower or below the upper one. At the moment, it is always drop below the upper one. But especially when stoa is all the way up and stob all the way down in the backlog, this result might be surprising.

Kunagi should either recogniize gestures more precisely.

Acceptance tests
