Project environment changes are not propagated to Run environment

After making changes to the environment variables in the Project > Project Settings > Environment tab, namely changing QT_LOGGING_TO_CONSOLE to QT_FORCE_STDERR_LOGGING as suggested by Qt warning in the console, it has changed under the Build Environment section in the Build & Run > [SomeQtKit] > Build tab, but not under Environment section of the Run tab of the same Kit.

Run Environment is set to use Build environment as its base, while Build Environment in turn uses System Environment.

When actually running apps, they indeed use unpropagated old environment as displayed, so at least it is consistent with what it shows and how it runs. But I can't seem to force it to apply changes.
