Right clicking in "Open Documents" switches mode

1. Run Qt Creator on Windows.
2. Open a .ui file.
   I used the one from qmake- and CMake-based Qt Widgets Applications created with Creator's wizard.
3. Switch to Edit mode.
4. Show Open Documents view.
   The file appears there.
5. Right click the file in Open Documents view.
   Creator will switch to Design mode immediately. This can be annoying e.g. if you just want to close the file or open a terminal.

Instead, Creator should stay in Edit mode in this case. This is the same issue as QTCREATORBUG-7054 which was meant to be fixed.
