Bug report

Since 1.10.0 I get a new error
Match arm comparison between 'B' and 'B' is always true
which shouldn't occur when we're using treatPhpDocAsCertain: false option.

Code snippet that reproduces the problem

Expected output

No error since the native type is string.

Did PHPStan help you today? Did it make you happy in any way?

The new @var validation is awesome.
