Why does Tfs2010 build my Wix project before anything else?

Following Rob Mensching's edit of my original post, it seems that this has indeed been fixed in WiX 3.6.0917.0 at the latest.

Its a bug, a bug, a bug. I don't know, who is responsible, but here's a working dirty filthy hack:

1. Open your .sln file in notepad.
2. Find your wix projects in the list of projects.
3. Cut them out, and paste them back after all other projects are listed.
4. Cry in the shower as you try to scrub the dirty off, only to emerge hours later, rubbed raw and still with the stench of filth clinging to you like corpse's skin.
