Microform js once issue

On a site I'm looking at the microform is not initialized.
changing this:
$(once('cybersource-processed', '#commerce-checkout-flow-multistep-default', context)).each(function () {
to this:
$(once('#commerce-checkout-flow-multistep-default', context)).each(function () {
fixes the issue, unsure if this is the right way to go about it, but patch is attached.
