Switching between models with an reference image uploaded makes it dissapear

Issue

Switching between models while a reference image is uploaded causes the reference image to disappear after returning to a previously selected model.

Steps to reproduce

1. Select Firefly Image 5 and upload a reference image.

2. Switch to Flux 2 [Pro] — the reference image remains active.

3. Switch to Firefly Image 4 — the reference image disappears.

4. Switch back to Firefly Image 5 — the reference image is still missing.

Expected behavior

The uploaded reference image should remain available when switching between models that support reference images.
