Bug ID: 51159
           Summary: test_NLSVersion() fails on Windows 10 >= 2004 in
                    kernel32:locale
           Product: Wine
           Version: 6.8
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: kernel32

test_NLSVersion() fails on Windows 10 >= 2004 in kernel32:locale:

locale.c:6900: Test failed: IsValidNLSVersion succeeded

This is the test where dwNLSVersion is decreased compared to its initial
version:

info.dwNLSVersion -= 0x200;
        ret = pIsValidNLSVersion( COMPARE_STRING, L"en-US", &info );
        ok( !ret, "IsValidNLSVersion succeeded\n" );

Traces show that Windows 8.1 to Windows 10 1809 have NLSVersion=6020f,
while Windows 10 >= 2004 has NLSVersion=60305.

Maybe the test fails because the older Windows accept anything in the 602xx
range and 60206 (60305+1-0x100) falls in that range?
What was the point of that test?

This test was introduced by the commit below:
