Slurs in cross-staff notation

I crossed several scores with cross-staff notation and I wanted to test MU in that use case.
I started from an example found on Youtube:

(source: youtube)

And I tried something in the same vein:

The result isn't that nice:
* the slur of the RH-voice 2 (green) crosses the LH-voice 1 (purple) when pushed to the RH staff,
* the slur of the LH-voice 1 (purple) doesn't follow the notes pushed to the RH staff

And the little dotted lines (very usual) are missing.

Is there any setting to control this ?
