Comment 22 for bug 1475205

According to Qt guys feedback https://bugreports.qt.io/browse/QTBUG-47547
Bug is marked as P2(Important, Not urgent, should be fixed, but will not stop the release), which doesn't fit our OTA release cycle since we can't wait for next release of Qt.
Thanks to Yc for correcting the "affects distribution/package"
qtdeclarative-opensource-src (Ubuntu) ---> qtbase-opensource-src (Ubuntu)
I try to submit my merge proposal for qtbase-opensource-src, but it doesn't work out since I am not a members of Ubuntu branches.
So I attach the patch here and send an email for stakeholder about this.
