trim fails on specific wire

with BuildSketch() as t1:
    with BuildLine():
        l1 = Polyline((10, 20), (-20, 20), (-20, -20), (10, -20))
        RadiusArc(l1 @ 0, l1 @ 1, 25)
    make_face()
arc = RadiusArc((10, 20), (10, -20), 25)
outside_curve = t1.sketch.edges().sort_by(Axis.X)[-1]
# outside_curve = arc.edge()
offset_curve = outside_curve.offset_2d(10, side=Side.RIGHT, closed=False)
show(outside_curve, offset_curve)
trimmed_curve = offset_curve.trim(0.2, 1)

trim fails when outside_curve is created from the sketch but not when directly from RadiusArc.
