Looks correct here with master, looking at the misrendering, I think it is this
bug:

commit e41dffb329e4a6fcb4e75fb501843838a499c4c8

    If the join indicates the pair of edges are parallel, we may be
    considering the final segment of the spline with a different tangent
    vector than the slope of the final edge and so lead to false dropping of
    an edge. This has the effect that the line segments between 'arc arc arc
    arc' (a rounded rectangle) are no longer horizontal or vertical. As path
    construction tries to eliminate joins between colinear segments, this
    optimisation should not be required anyway.
