Description
Describe the bug
Copy-pasting history stack doesn't paste shape masks in modules. The parametric mask is copied, but the shape is not copied. When opening the module in darkroom, there it states in drawn mask: no mask used. This also applies to retouch module, where the retouching shapes are not copied.
Steps to reproduce
- Open an image and add a module where you also apply a geometric mask
- Create a duplicate of the image and erase the history stack
- Copy-paste the history stack from the first image to the second
- See the difference, the module is applied to the full image, not only the restricted area
Expected behavior
The geometric masks should be copy-pasted with the associated modules
Logfile | Screenshot | Screencast
The first image has a second exposure module applied with a geometric mask (see the dark spot). The second image has the history stack copy-pasted. The full image is darker, not only the spot in the middle.

Please provide additional context if applicable. You can attach files too, but might need to rename to .txt or .zip
I haven't been able to test as I have build issues with my Fedora 38 (#14527).

Research direction
Start by reproducing the history-stack copy/paste workflow with a geometric mask, including a retouch module, using the listed steps. No source file, test, or entry point is named, so trace the history-stack copy/paste path and the associated module mask data. Done means copied modules retain their geometric or retouch shapes when pasted and the existing behavior is covered by a regression test.
