There is an addon on Curse Forge that is called Grounded (https://www.curseforge.com/wow/addons/grounded)
It worked in official WotLK and now works perfectly in official Cata Classic and Vanilla Classic but when I tried installing it for Warmane, it didn't work.
I even tried different versions and adjusted the game versions in .toc files but it didn't help.
The @cursor macro condition doesn’t exist on this client, so the addon is useless. Simply updating the TOC won’t help—you’d need to modify code to adapt to this client’s older API.
