Alx Sa a331caa9f2 core: Enable resize for GUI layer duplication 
Resolves #13633 (for now)
Same rationale as 975d1a4a, as diagnosed by Thomas Manni.

During 3.2 development, we can review and likely just set this as
the default value inside GimpDrawable.
For now, this is a limited bugfix for 3.0.x.
