[REG] Documentation no longer shows the relationship between qml types from different modules

gbk (QTBUG-77126):

This one is about QML type inheritance which qdoc gets from the \inherits command. Apparently, it's no longer working across module boundaries.

kot:

I'm develop osgQtQuick project:

https://github.com/podsvirov/osgqtquick/tree/develop

And use qdoc to generate documentation:

https://podsvirov.github.io/osgqtquick/osgdoc/index.html

The project consists of several modules, and before with cross-references between modules everything was fine.

I try to upgrade to version Qt 5.12, but the inheritance from types from other modules has stopped working.

I have the impression that the \inherits command stopped recognizing the full type names with the module name prefix.

An bug has been observed since version 5.8.
The qdoc tool version 5.7 is working as expected.
