Bug report

Since PhpStan 1.8.3 I get a false error message
Static property Demo\CountryMapper::$countryISOMapping (array<literal-string, all-enum-values>) does not accept default value of type non-empty-array<literal-string&non-falsy-string, literal-string&non-falsy-string>.

In versions up to 1.8.2, phpstan did not complain, and I triple checked.

I couldn't come up with a minimal test case, so I have included the original source in https://github.com/tlamy/phpstan-1.8.3-issue .
