Translations: Window titles display multiple Length Variants instead of selecting a single one

See attached project, which is a modified version of the Hello tr() Example (https://doc.qt.io/qt-6/qtlinguist-hellotr-example.html ). It  contains 2 length variants of the translated text, and echoes the same translation to the window title.

While the QPushButton correctly selects the variant based on the widget size, the window title shows BOTH variants concatenated.

Notes

Qt Quick window titles are also affected.
