BUG: BCBREAK 13.2.0 - E-Mail subject in admin confirmation not populating registration data anymore from TypoScript setup

[griesi007]

until 13.2.0 it was possible to use registration data in the createAdminConfirmation E-Mail subject in TypoScript as follows. This does not work anymore with 13.2.0.

I was not able to determine whether this was an intentional BC break and if there is an alternative in place?

plugin.tx_femanager {
	settings {
		new {
			email {
				createAdminConfirmation {
					subject = TEXT
					subject.data >
					subject.value = {field:company} {field:country}-{field:zip} {field:city})
					subject.insertData = 1
				}
			}
		}
	}
}
