Please see this bug report:
https://bugreports.qt.io/browse/QTBUG-65145

And this corresponding fix:

Any way to get this included in a Ubuntu 18.04 package update?

This bug is fixed in Qt 5.12.3 and newer. The current LTS version, Ubuntu 20.04, has Qt 5.12.8. So this bug is already fixed for some time.

Unfortunately I don't have time to support older releases like 18.04.
