1. Create a Qt Quick Application project in Qt Creator.
2. In the project's QML file, add some JavaScript with a failing condition:
   I have:

       MainForm {
           anchors.fill: parent
           mouseArea.onClicked: {
               console.log(qsTr('Clicked on background. Text: "' + textEdit.text + '"'));
               if (textEdit.text == "key")
                   console.log("Unlocked");
           }
       }
   

3. Put a breakpoint into the first line of this JavaScript.
4. Run the application in the debugger and let it stop at the breakpoint.
5. Step forward twice.
   Creator will indicate that you stepped into the line with the second log although this line is not being executed.

Stepping should only reach lines that are being executed.

It seems like the debugger will always indicate being stopped at the last line of the block. If you add another line after the second log (outside the "if"), the debugger will step to this instead.
