Hmm.. maybe the "Undo Discard" button could be underneath on its own?

It will make the list jump when it appears, but currently not a bit issue since the button keeps staying forever. Also Remove "Undo Discard" affordance after committing should be fine because you're focused on the commit button and not the list.
