Landscape format snapshot gets rotated by 90° when activating it on a portrait format image (and vice versa)

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

In darkroom, I create a snapshot of a landscape format image. Then I switch to a portrait format image and activate the snapshot taken before. The snapshot now gets rotated by 90° to the left. The other way round, a snapshot of a portrait shot gets rotated 90° to the right, when activated on a landscape take.

Steps to reproduce

see above

Expected behavior

darktable should keep the orientation of the snapshot taken

Start in darktable's darkroom by reproducing the snapshot activation sequence with landscape and portrait images. Trace the snapshot activation and orientation handling, then verify that activating a snapshot preserves its original orientation in both directions.
