Copying and pasting module order has side effects - or selective copy/paste broken?

[kofa73]

Describe the bug

Selective copy/paste (of module order?) has side effects. See more below.

Steps to reproduce

1. Get the raws and the sidecars from https://tech.kovacs-telekes.org/files/2023-10-15module-order-copy-paste-side-effect/ (note: 2023-09-24-10-09-05_P1010579_05.RW2.xmp is a lighter stack for the 2nd image; the screenshots were made using the original stack, 2023-09-24-10-09-05_P1010579.RW2.xmp, so your output will be somewhat different, but the effect is still obvious),
2. Import them to darktable,
3. Open 2023-09-18-19-49-32_P1010520.RW2; check the module order - it should be custom (filmic and sigmoid have been swapped for this demo):
4. Open 2023-09-24-10-09-05_P1010579.RW2. Check it module order; should be v3.0 RAW; the history stack should have 20 elements, the last one being sigmoid(with the _05 stack, 14 modules, the last being crop):
5. In the lighttable, select 2023-09-18-19-49-32_P1010520.RW2, duplicate it, then use Ctrl+Shift+C, keep only module order; copy the stack:
6. Select 2023-09-24-10-09-05_P1010579.RW2, use Ctrl+Shift+V, keep only module order; paste the stack:
7. Observe that the duplicate is flipped around, and its aspect ratio changes:
8. Open the duplicate. Its stack contains 37 (with the _05 stack, 32) elements. Above the original sigmoid (entry 20), we have:

Expected behavior

darktable should only apply the selected item: module order

Can reproduce with 4.5.0+1014-g5f25f79812, Ubuntu 22.04

• Happens also if copy is done in darkroom, if the stack of the source image is minimal, if other images are used or if the copy is done the "other way round" (read: copy V3.0 RAW over custom).
• Does not happen if only one additional item is added to module order (two items copied, for example module order and crop)
