Once again: how is my *current* patch related at all to what you request?

I said not good *enough*, I never said they are not good, so stop
accusing me about something I didn't say. And if I had tests ready, I'd
already send this *unrelated* patch. I will learn to not share with you
WIP diffs if you don't understand what they are.

And well, if it matters that much to you, your tests are nice for
overview of the bug, but it's hard to point the exact problem from them,
so more detailed tests written with implementation in mind are needed
and that's how I discovered the problem I'm fixing. They also show that
we're only interested in only WS_CHILD style (and usually just for
wine_todos), so calling them for all style combinations feels a bit like
out-placed shooting in the dark, not showing the exact problem. More
detailed tests are required to show exact problems with WS_CHILD in
dialog templates.
