Steps:
- create mesh, add Basis shapekey and another, second Shapekey with full 1.0 weight
- change mesh with second shapekey in edit mode
- switch to sculpt, try to draw facesets on changed parts. They are not drawn at all. Same with other facesets-drawing tools
Facessets are ok on unchanged parts, but not added on shifted faces
