The new design (with the assistant/model select in the text field) doesn't let me change the model used when editing a message. Was a huge help when trying to evaluate models.
And unrelated to the bug, but I'm really not a fan of moving the model selection from the top (next to the tags) into the text field. It's incredibly annoying, constantly disappearing only to reappear when you briefly pause typing. It also made it harder to see which model any given chat uses, since you now have to scroll up to the last response, instead of instantly seeing it at the top.
Ideally this could either be reverted or added as an option.
