Stopping debug on mixed debugging fails for MinGW

created simple Qt Quick app (used the compat version)

added bp inside the cpp and added some code to the qml file to be able to hit a bp there as well

started debugging, QC stopped correctly at the bps - in both cases Continue

using now Stop debugging does not work (no matter whether triggered on the QML debugger or the GDB debugger)

Using Stop on the application outputpane also did not really help, but closing the app output pane for this app made the debugger return to stopped/finished state
