Boot2Qt/CMake debug configuration has QML debugging (re)set to "Default"

Set up Boot2Qt. Create a CMake based project with the kit. Various kinds of build configurations are created.

The Debug configuration starts out with the QML debugging option set to "Enable", but after the CMake configuration it resets to "Default". Starting debugging with QML breakpoints set complains about the debugger not being able to handle some breakpoints (the QML ones).

I have to manually set the QML debugging option to "Enable" and run CMake again to be able to debug QML.

This works correctly for Desktop kits (QML debugging options starts out as "Enable" and stays that way).
