"/macroicon" function buggy with "Jump"

I was directed here by SE support.

I've built numerous macros for my Dragoon class. The first line of each macro is "/macroicon SkillName", and they all work as designed with exception to the Jump macro.

While it will execute the Jump command properly, the macro's icon is the generic grey "M" and does not show the cooldown.

Yes, I have tried putting it in quotes, and other variations to no avail.

My guess is that the /macroicon function is unclear about whether to use the icon for the Dragoon Jump skill or the universal Jump action while traversing.
