Subject: [PATCH] dev-qt/qtdeclarative: backport fix for QTBUG-142514

Fix seems rather trivial so risking straight-to-stable to avoid
churn and deliver the crash fix to stable users earlier.

Note fix is not in the 6.10 branch yet wrt 6.10.9999 but the
backport should happen soon. Odds are that it will not be added
to the 6.10.2 branch so the patch will be needed until 6.10.3.
