Required for !1857 to not break when comctl32 version 6 isn't requested by application (in particular, found this in [qapitrace](https://github.com/apitrace/apitrace)).
Manifest resource id and assembly identity name match with Windows.
For isolation purposes, activation context is disabled while emitting events.

Did we (or someone else) decide that `0` is always an invalid cookie?

Don't remember, think it was us, current implementation wise (I know, shouldn't rely on that too much), it's a pointer to a heap allocation, which I assume can't have `0` as a valid value.

I'd say the heap allocation thing is a hack in Wine. It looks like Windows have sequence numbers for cookies instead. If we ever have an app that relies on `0` being returned on newly created threads or fibers, then we won't be able to fix the app without regressing, until all callsites that assume `0` is an invalid cookie is fixex.

The cookie checks and ERRs are not useful, you can simply assume that the calls will succeed.
