There seem to be a small bug in the upscaling tab.

When I have Flux Kontext selected in the model in the Refine section (inherited from generate's currently active), Even when it is ticked off, I get this message :

Error: Internal assertion failed [Edit models do not support upscaling]

Fixed by ticking on "Refine upscaled image", changing to a model like Flux dev, then unticking.

Expected :

Logic checks if the Refine upscaled image box is checked before asserting the model type
