Badly formatted output of "Run Checks"

1. Start Creator with Qt in PATH and empty settings, e.g. using the parameter "-tcs".
2. Make sure that the created Desktop kit uses gcc as compiler.
   I used the distribution's gcc 11.
3. Create a new Qt Quick Application project using Creator's wizard.
   Creator will show Main.qml which contains a Window item.
4. At the end of the Window item, before its closing brace, add the line:

   Color: "blue"
   

5. Save the file.
6. From the menu, select "Tools" -> "QML/JS" -> "Run Checks".
   The issues view will appear and look like this:
   
   Some formatting seems to go completely wrong.

This does not happen, when the kit uses clang as compiler.

Found while updating tst_QMLS02.
