Literal string array keys incorrectly cause error that makes no sense and wrong tag?

[kkmuffme]

/**
 * foo
 *
 * @param array<'hello'|int, string> $a xyz
 */

is an InvalidTag of type method (?) with message

An array can have only integers or strings as keys

Works fine in phpstan https://phpstan.org/r/7a29b6c5-52de-4762-aa0a-2e03deb5acaf (and has worked fine in v1 since ages too)
