Comment #10 says the exact opposite -- that wine is acting in the way it does to work around the behavior of other window managers; and that the behavior of wine is wrong but correcting it is not trivial.
I don't see where it's been stated that current Wine behaviour is wrong, otherwise it's been said that Wine already does a lot of efforts to workaround the WM bugs, and even more workarounds is needed since apparently there are more broken WMs around. And yes, it's not trivial make Wine run correctly on broken WMs.
