I think there's a bug here: https://github.com/fulcrologic/fulcro-rad/blob/a490af7dea1d094ee4d2703806f16a9ab70351a6/src/main/com/fulcrologic/rad/form.cljc#L397

When silent-abandon? is true, it runs (uism/trigger! app-ish form-ident :event/exit {}) twice

I think line 406-407 should be deleted

Also it looks like the ::form/confirm option doesn't have an entry in the form-options file: https://github.com/fulcrologic/fulcro-rad/blob/a490af7dea1d094ee4d2703806f16a9ab70351a6/src/main/com/fulcrologic/rad/form.cljc#L464
