Exposure selected area not saved

Is there an existing issue for this?

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

Describe the bug

When I use the automatic exposure based on selected area on a picture (picture A), then I switch to another one (picture B), the selected area by default is the one set on the previous picture.
But if I set a new area for picture B, then I go back to picture A to see the area, it's the one from B that applies.

Steps to reproduce

1. Go to picture A
2. Enable exposure adjustment from a selected area
3. Select an area
4. Go to picture B
5. Enable exposure adjustment from a selected area (it shows the one selected for picture A by default)
6. Fix the selected area to better fit picture B
7. Go back to Picture A
8. Click again on exposure adjustment from a selected area (the one from Picture B applies)

Expected behavior

Each exposure module on each picture should save its own area

Start by reproducing the eight steps in the issue with two pictures, checking whether the selected exposure area is retained separately for each picture. Trace the exposure-adjustment entry point and its per-picture state, then verify that returning to picture A restores A's area while picture B retains its own.
