Description:
Re-import of an exported MusicXML score exhibits differences in the 'beaming' of eight notes.

How to trigger:
Load score test03.mscz (see screen shot [test03-mscz.png]) and export in MusicXML format. Loading MusicXML score test03.musicxml results in a different eight notes beaming (see [test03-MusicXML.png]).

Comments

This behaviour changed between 2.1.0 and 2.3.2. Note that, due to differences in their data models, it is not always possible to save a score to MusicXML and import that score from MusicXML without a difference to the original. For beams this probably would be possible, but am not yet convinced it would be desired.
