Suppose we have this kind of basic python package:

where robot_interface.py contains class MyModuleB and __init__.py from robot_interface imports MyModuleB.
Robot Framework fully supports that scenario, but the plugin does not.
So, when looking for the correct class in the imported Library, the plugin would also have to look into subimports.

Please also refer to the full example here to reproduce the issue:
