    """ Check edge case behavior to detect upstream changes
    For edge cases where a pixel has the same distance to several regions,
    lexicographical order seems to determine which region gets to expand
    into this pixel given the current upstream behaviour in
    scipy.ndimage.distance_map_edt.
    As a result, we expect different results when transposing the array.
    If this test fails, something has changed upstream.
