Bug: Multi-model select modal goes away when switching back and forth from create page

Context via Efreak on Discord:

I think visibility if the multi-model check box is still getting lost switching back and forth from img2img and main tab, btw.

Not internal state, but the check mark itself and the display of which models are chosen. Yes, I just checked again, that's exactly what happens. Same happens when I go to image list, pending, etc. It doesn't actually lose the list of models I have selected, so it's just a visibility issue
