Guess what? The font difference is due to the Qt::AA_Use96Dpi flag that
is set on the QApplication by the QTEST_MAIN() macro.
It looks like this flag is not properly handled by all code paths, so
setting it affects QtQuick's font rendering but not QtWidget's.

Anyway, setting this flag to `false` at the beginning of my tests seems
to fix the issue.
