Rucio query is not able to see files that are in datasets.

This is not a problem for me right now, but it may be behaviour that is not what users expect. I created a few files in Rucio of which soome are in a data set and some aren't. If I query the Datalake using ESAP, I can only either find the files that are not in a dataset, or the datasets. But it does not show me the files that are part of a dataset, even if I force it to look for files.

(mostly reporting so the bug is documented, I do not need the functionality right now).
