Emojis rendered with CompositionMode_Source results in transparent hole around glyph

painter.setCompositionMode(QPainter::CompositionMode_Source);
painter.fillRect(rect, m_pressed ? QGradient(QGradient::OverSun) : m_brush);

painter.drawText(rect, Qt::AlignCenter, u"Hello from QWindow 👋"_s);

We should make the emoji drawing match the non-color glyphs.
