    Expected substring: "8 : M117C1-ch_2.fq.fastqsanger"
    Received string:    "8: M117C1-ch_2.fq.fastqsanger"

otherwise looks good

Yeah, figured I'd need to update a test or two -- will follow up in a minute. Thanks!

Updated the two tests that needed it for the new format; integration test passes locally and is waiting on something in a different interface.

It seems this broke 2 Selenium tests on dev?

FAILED lib/galaxy_test/selenium/test_history_dataset_state.py::TestHistoryDatasetState::test_dataset_state - AssertionError: 1:

@nsoranzo I'll take a look; I thought I had addressed the only failing test here. (oof -- I may have fixed one of two selenium suite failures; I'll follow up in a quick PR)
