Subject: [PATCH 22/30] Revert "QQuickItem: Fix effective visibility for items
 without parent"

This breaks applications that use QQmlPropertyList to store QQuickItem
and don't set a parentItem for them.

Ref: https://github.com/musescore/MuseScore/issues/17276

This reverts commit 45c22a0221937682f4496801a495458a00f76d3a.
