Research direction

The issue is that the 'borderColor' shorthand property is not being expanded to include 'borderRight' in the sorted output. Investigate the jss plugin props sort source code (likely in packages/jss plugin props sort/src/index.js) to see how CSS properties are sorted and shorthand expansions are handled. Check if there is a missing mapping for 'borderColor' to include 'borderRight'. Additionally, look at the linked sandbox for reproduction. The fix may involve adding 'borderRight' to the list of properties that 'borderColor' should map to, or adjusting the sorting logic to handle CSS shorthands correctly.
