These tests show that it's the themed property sheet page window procedure that sets device contexts
transparent and return a pattern brush created from the tab body part in a theme. Combined with
test_WM_CTLCOLORSTATIC() in dlls/comctl32/tests/static.c, we can conclude that UXTHEME_DefDlgProc()
shouldn't handle WM_CTLCOLORSTATIC.
