[REG: 5.12 -> 5.13] QRasterPaintEngine listed in 'All Classes' has no .html page

https://doc.qt.io/qt-5/classes.html#r

lists QRasterPaintEngine, but the link goes to 404.

It works in 5.12:

https://doc.qt.io/qt-5.12/qrasterpaintengine.html

The fact that it's not generated in 5.13 is expected as it's declared in a private header, but then it should not be listed in the 'All Classes' or module pages. Maybe something to do with \preliminary?
