Gliss text off-centered upon PDF and PNG export

I know that this is a little over the top to call it major, but since MuseScore's #1 priority is producing beautiful looking scores, this should be considered something important to fix since it has to do with visual score output, albeit something simple:

Exporting to PDF/PNG is not resulting in centered text as it shows within MuseScore itself.

Although no feedback has been given yet, here's a forum post showing this along with an included mscz and corresponding pdf showing the distinction.
