It's not any UAs that support the unprefixed name. It's that many
authors have already begun using it in conjunction with prefixed
names as a way of preparing for more widespread implementation.
Changing the name now wouldn't actually break anything right now,
but it would be confusing. If we want to change the name of these
properties, we'd have to weight the benefit of the name change
against breaking authors' expectations.
