As usual I want to personally extend my gratitude to the Commercial users of Qt for beta testing Qt 5.15.7 for the rest of us.
The Commercial Qt 5.15.7 release introduced one bug that has later been fixed. Thanks to that, our Patchset Collection has been able to incorporate the revert for bug  and the Free Software users will never be affected by it!
