Augm. dot misplaced for low stemless notes
OS: Linux Mint 17.3. Since at least ver. 2.2.1, the augmentation dot for stemless notes below the middle staff line is misplaced. Example from latest PPA version (2.2.1+dfsg1-5~ppa1804+1; 2.3 AppImage result is identical):

For comparison, the same score as engraved by 2.1 AppImage (which I luckily happen to still have installed):
