Build environments for Msvc build configurations don't inherit QtCreator's process envoronment

I launch Qt Creator from a terminal or from Qt Creator with a modified (run) environment that has extra entries in "Path". I chose a kit for a project in the launched Qt Creator and usually the aforementioned environment/path modification would appear in the project's build configuration.

This does not seem to be the case anymore for projects using an Msvc kit, with Qt Creator master.

If works as expected in Qt Creator 11 and with Msvc kits. It also works as expected with MinGW kits in Qt Creator master.

So, it seems that the combination master/Msvc kit is the faulty one.

Addendum: All of this is with CMake projects
Addendum #2: The same happens with Qbs projects. So, I guess this is Msvc toolchain specific (in master).
