R127:1934ea48cd1d: [server] Add a workaround for a freeze in QtWayland
Summary

See: https://bugreports.qt.io/browse/QTBUG-52092

Freeze happens if a sub-surface is rendered to before the main surface
is rendered. The compositor has no chance to know that this is a window
which needs to be rendered, thus the application might freeze without
ever becoming visible.

Famous example applications being affected: all kcms with a nested
QQuickView. E.g.: kcmshell5 kwineffects
