PropsSI ("D", "P", valueP, "T", valueT, "R407C") return bad result in L+V Phasis

[pmanach]

Examples :
PropsSI("D","T",285.71,"P",787580,"R407C") = 1188.45
PropsSI("D","T",285.71,"P",787580,"REFPROP-R407C") = 81.40

Seems like it is not erroring out properly when inputs are two-phase.

In [1]: import CoolProp

In [2]: CoolProp.CoolProp.PropsSI("D","T",285.71,"P",787580,"R407C")
Out[2]: 1188.4479808551962

In [3]: CoolProp.CoolProp.PropsSI("D","Q",0,"P",787580,"R407C")
Out[3]: 1196.8777409588633

In [4]: CoolProp.CoolProp.PropsSI("D","Q",1,"P",787580,"R407C")
Out[4]: 33.56169650226702

In [5]: CoolProp.CoolProp.PropsSI("T","Q",0,"P",787580,"R407C")
Out[5]: 283.62553230284266

In [6]: CoolProp.CoolProp.PropsSI("T","Q",1,"P",787580,"R407C")
Out[6]: 289.48763809255865

so those inputs are two-phase

And now:

In [1]: import CoolProp

In [2]: CoolProp.CoolProp.PropsSI("D","T",285.71,"P",787580,"R407C")
