deprecated typealias does not show up as deprecated

Description

Note the ConcurrentValue missing the red Deprecated marker even though it is deprecated. The marker properly shows up in the description page, but not on the left hand side listing

// Historical names
@available(*, deprecated, renamed: "Sendable")
@available(swift, obsoleted: 6.0, renamed: "Sendable")
public typealias ConcurrentValue = Sendable

@available(*, deprecated, renamed: "Sendable")
@available(swift, obsoleted: 6.0, renamed: "Sendable")
public typealias UnsafeConcurrentValue = UnsafeSendable
