    Confirmed in master. A workaround is to constrain the angle of r005-line-segment to the X axis, not the YZ reference plane.

    This is not longer (ver 3.1x) flagged as redundant, but the sketch still breaks easily unless we delete the angle constraint. It can be constrained against a horizontal line fine, but changing the angle value then breaks it (red).
