[BUG!][SOLVED] SubShape binder not tracking orientation of its source?

[Grawp]

Hello,
Perhaps it is not completely correct for me not posting this in Help on using FreeCAD but here I hope it'll get more attention from people who might know something more about Links and SubShape binders

Here I have my model:

Where in x the Binder is tracking the Sketch from the linked Panel and it is extruded.
However, after I rotate the linked Panel everything goes to hell:

The Pad becomes skewed but this behavior is NOT limited to pads. Projections into sketches from the Binder would get broken, things attached to it would get wrong attachment like the source object being not rotated at all.
This goes even for Inertia23 mode which should give a damn about some underlying orientation of sketch/link/whatever and consult just the geometrical elements e.g.:

I've found almost nothing about SubShape binder on the bug tracker. Any help is appreciated.

PR submitted here.

It is not really about the SubShapeBinder, but FaceMakerBullseye (i.e. the face maker used by binder to create face from sketch) instead.

I've built the PR and it works!
Thanks
