Short description of error
Create any object, for ex cube (click add->mesh->cube). Add armature to the scene (click add->armature). Add armature modifier to the cube. In the modifier settings select created armature as deforming object. Then go to the sculpt mode, try to draw face set on the cube, notice it does not work.

Apparently Face Sets don't work with some modifiers.
The manual doesn't say much: https://docs.blender.org/manual/en/dev/sculpt_paint/sculpting/editing.html#face-sets
@Pablo Dobarro (pablodp606), is this a known limitation?

Will confirm for now, needs @Pablo Dobarro (pablodp606) to make a final call though.

Draw Face sets now uses the deformed PBVH coordinates to calculate the face center, so it should work both it shape keys and armatures.
