Swing and Staccato information get's lost when exporting parts to midi

I use Musescore for composing and generating midi tracks - one per part - to be imported to my DAW (Reaper in this case). I realized that the staccato point is not respected in the midi file by shortening the note length.
Recently I exported a midi file containing SWING notation. The resulting midi file plays straight eights although it plays swing eights in MuseScore.

Is this problem known?
