This looks good, I can't find any other more "official" way to do this in the Formik docs so I think this is the best solution. I've tested it briefly and cannot find any adverse effects, it seems correct to me.

p.s. please add the missing semicolon to fix the CI :)

LGTM and I assume no accessibility issues, since it's local to the "leaf" nodes of nested forms.

FYI Saksham found some issues with the enter key not working to click on buttons around the form. So this is still a WIP for now
