PartDesign: Select plane to attach sketch-> Sketch has wrong orientation

### Problem description

In some cases, sketches get not attached correctly at plane faces of lofts.

### Workbench affected?

Part Design

### Steps to reproduce

If I try to attach a new sketch in partdesign to a plane (in this vase created by a loft), the orientation in some cases is flipped (see attached model):
If You open the attached FreeCad File You see a plane which is built by a loft with some arcs over it (see pic 1).

You look to front. If You attach a sketch to this plane, the sketch is opened, but it is in top direction, not in front direction, see pic 2

### Expected behavior

Sketch applied in the correct direction

### Actual behavior

Sketch flipped
