jena-arq: FROM / FROM NAMED clauses of SPARQL queries over in-memory Dataset are ignored

Hi, It appears that the FROM / FROM NAMED clauses of SPARQL queries are ignored when executed over a Dataset. In the example below, I would expect the first result set to yield the content of the file, whereas I expect the second one to be empty as the specified named graph does not exist, yet
