Elements v22: sendtoaddress to a confidential taproot address does not blind the output

[tiero]

I am using elements v0.22 and using sendtoaddress RPC to send to a confidential taproot address, Elements seem to fail to blind, and tx results in full unconfidential

elements-cli sendtoaddress el1pqwp9ze75659cn5ad0hw25nt2kv7j882gudn636hnh4qvjcmjh6jq5ca0d4cgl009m5rn5w0n3k2cqa3ths2qf7s8q6x2xplwgvlfhg0atxwjah9089tf 0.1

The address is a valid segwit v1

elements-cli validateaddress el1pqwp9ze75659cn5ad0hw25nt2kv7j882gudn636hnh4qvjcmjh6jq5ca0d4cgl009m5rn5w0n3k2cqa3ths2qf7s8q6x2xplwgvlfhg0atxwjah9089tf
