Bug report

This is contrary to how level <=6 is supposed to work.

Code snippet that reproduces the problem

https://phpstan.org/r/c0fc78fc-9633-4e54-8888-f4426aa6e83c

Expected output

No PHPStan error, at least when nullable type (passing type unined with null) is passed for level <=6.

Also, as I had to dump the input type myself when debugging, I would welcome the "Unable to resolve the template type..." error message to contain the given type to be able understand the problem quickly just from the message.
