Please explain how I can file a bug report against the built-in comctl32 component, as Nikolay Sivov suggested (it makes sense to me).
The rule is one problem per bug report, and problems with native dlls for which Wine has a replacement are not generally considered valid bugs. File a new bug report for each problem with builtin comctl32.
