Fixes#11842.
The `once: true` was likely added to prevent multiple concurrent
submissions of the same form. This could still be worth preventing,
but I suspect it would require wrapping the supplied `onApprove`
callback with the corresponding logic, implemented manually, as I
am not aware of any native API to prevent concurrent executions of
callbacks.
