Click on metadata_sources schema => no display.

Console output:

This was fixed in subsequent changes to the display-schema content, but the fix was not explicitly documented.

NOTE: The display schema functionality could perhaps be useful to refactor and extract into its own package at some undefined point in the future. But this is not a priority for future datalad-catalog developments.
