The issue I'm referring to that images are scaled to be larger than they actually are (i.e. if it's 16x16, it would still be stretched to a size larger than this, which looks bad because it is pixelated). The issue where images are scaled in such a way as they do not maintain their aspect ratio is what was fixed and is in the latest public hotfix.

I believe that this newer issue has also been addressed, though I don't think it has been released. You should contact Developer Support so that you can be notified when the fix is made available.
Hmm I have the hotfix 20083_HotFix_2021 but it it still stretches the images but they get stretched with fixed aspect ratio. Looking at your pic, expand the width of the "S"-column and you will get a streched image in the first row.

This was fixed by recent HotFix
