"Find symbol under cursor" can't find QProcessPrivate in .cpp

Built from commit 08f8dd355d7a0e952707418ba6e86d18c6c47b2f.
Steps to reproduce:

1. open qtbase's CMakeLists.txt
2. wait for parsing
3. open qprocess_unix.cpp
4. find any "QProcessPrivate" and press Ctrl+Shift+U

Expected results:

• content of qprocess_p.h and qprocess_unix.cpp is shown
• preferably, content of qprocess_win.cpp is shown too

Actual resutls:
Only results of qprocess_p.h is shown. See Note how it doesn't find the cursor that triggered finding symbol under the cursor.
