Text vertical alignment is wrong when lineHeight is set with some non latin characters

In QML when using a Text item with:

• lineHeight is set
• The text contains some non-latin characters
• verticalAlignment is set to something else than Qt.AlignTop

Then the actual text rendering does not respect the alignment and can even render outside of the Text item.

I have tested with Qt 5.15.2 and 6.0.0 official builds and with Qt 5.15.2 provided by Arch Linux package manager.
