Issues with accent playback in swing time using expressive soundfonts

Issue: unusual playback of swung notes with accents when using an "expressive" patch from the MuseScore General soundfont. The second (offbeat) note, if accented, has a sort of echo effect, where the note starts off at a normal volume then only gets accented a little later. This does not occur when entering an equivalent rhythm in non-swung time (swung eighth-quarter vs. triplet quarter-triplet eighth non-swung) or when using the non-expressive patch.

Example in attached score: a non-swung eighth-quarter pattern that plays back as expected, a recreation of the swung rhythm in standard meter which also plays as expected, and finally the swung rhythm which has a sort of "bump" in the sound.

Note that I am using the sf2 version of Musescore_General rather than the sf3 version.
