grace note slurs do not upload correctly to musescore.com
S3 - Major
Slurs for grace note either do not show up, or endup rotated 90 degrees on musescore.com after uploading. Using MuseScore2 program.
Steps to reproduce the issue
1) guitar with TABS; drag and drop grace note (acciaccatura), move grace note one step down, drag and drop Line > Slur.
Upgrade to MuseScore 3(.2.3) amd try again, MuseScore 2 and its backend on musescore.com won't recieve further fixes.
