Highlighting of conditional compile with Q_OS_WIN64 does not change

1. Have some code like this in a project:

   #ifdef Q_OS_WIN64
       qDebug() << "This is 64 bit.";
   #else
       qDebug() << "This is 32 bit.";
   #endif
   

2. Configure this with a 32 bit Kit and a 64 bit Kit.
   Highlighting does not change when toggling the Kits, see screenshots.

Instead, highlighting should represent the bitness of the current Kit.
