This addon is no longer required.
In patch 12.0.7 Blizzard have stopped using SetTooltipMoney for Tooltip Money Display.
Temporary fix for Money Frame tooltip issues.
It replaces SetTooltipMoney with a standard tooltip addline. You will see the Sell Price text for items as light blue instead of white to show that the fix is in use.
Remove this addon when it is no longer required!
