Well, the event display of rosegarden does not agree with you, but
lilymidi --pretty does:

The question is whether this was recently introduced.  The last Midi
changes of some relevance would seem to have been

    Midi: store dynamic information for note-on velocity; issue 1661

commit 1c980a9906a7ea01b9f99487e75580f7232f2491

    Issue 2672/1: Midi fixes
    
    When other MIDI midi events (such as an instrument change) occur
    simultaneously with note(s), they should be placed in the MIDI file
    before the note-on events, otherwise there is no way to (reliably)
    affect the first note in a score.


Those would have appeared in 2.15.42.  Can somebody check whether we get
different behaviors between 2.15.42 and 2.15.41?
