ddraw:ddraw7 - test_lighting() sometimes fails on Windows:
ddraw7.c:4728: Test failed: Lit quad without normals has color 0x00ffff00,
expected 0x00000000.
ddraw7.c:4741: Test failed: Lit quad with normals has color 0x00ffff00,
expected 0x00000000.
ddraw7.c:4786: Test failed: Lit quad with light has color 0x00ffffff.
ddraw7.c:4786: Test failed: Lit quad with singular world matrix has color
0x00ffffff.
ddraw7.c:4786: Test failed: Lit quad with transformation matrix has color

See https://test.winehq.org/data/patterns.html#ddraw:ddraw7
The number of test failures changes from one run to the next, as well as the
unexpected color, although it's always a mix of ff and 00. This issue has been
there since at least 2023-01-20 and has happened regularly, about 1.5 times per
month, on Windows 8 to Windows 10 22H2.
