Image of the Font Family drop-down getting clipped

SUMMARY
When the Text Properties docker is somewhat short, drop-down menus that would extend outside of the docker are instead clipped to the docker's boundaries. This is in contrast to other dockers where menu widgets will go outside the boundaries to fit entries as necessary (QML related?).

STEPS TO REPRODUCE
1. Create a new document and open the text properties docker
2. Make the docker very short and then click on the Font Family drop-down
3. Observe the list getting clipped at the docker's boundaries.
4. This happens both when the docker is docked as well as when free floating 

This was tested with Qt Platform Name:  "wayland".
Attached is an image of the bug, along with additional system information.
