Mask layers were added (unnecessarily) in these cases: - calling `Mask Slice` without having a mask even (now return `OPERATOR_CANCELLED` early) - calling `Mask Extract` without having a mask even (now return `OPERATOR_CANCELLED` early) - `Extract Face Set` was also adding a mask layer (only because both extracts used `geometry_extract_apply`), moved mask specific stuff into `paint_mask_extract_exec` (see above also) Came up in !123888 Pull Request: https://projects.blender.org/blender/blender/pulls/133435
