[REG 7.0.2 -> 8.0] Can't Step Through JavaScript Code

1. Open the Samegame demo in Qt Creator.
   It's in Examples\Qt-<version>\demos\samegame\samegame.qmlproject of an installation from the official online installer.
2. Set a breakpoint in the first line of the function startNewGame().
3. Start debugging.
   Don't use Qt 6.3.1 or you'll run into QTBUG-104379/QTBUG-104400
4. In the demo, click "1 Player".
   The breakpoint is being hit.
5. Press F10 to step forward.
   The demo continues without stopping at the next line.

In Creator 7.0.2 this works correctly.
