new description:

qgis (the underlying libraries) is less forgiving then other programs when it comes to do geospatial operations (clips, intersections, etc.) when the input(s) have geometry issues. It would be nice to have an option to have them checked before running any of those operations, throwing a warning and/or cleaning them on the fly (options are not missing, lwgeom, pprepair).

old description:
Currently QGIS silently creates an empty layer if there are topology issues with the clipping layer. See #12144.

QGIS should at least issue an error with the description of the problem or fix the problem if possible.

You can easily achieve this by creating pre-execution script or models
