Enchantment Descriptions (version 0.6.1 for 1.18.1) item tooltips in REI are not fixed. Using ToolTipFix version 1.0.4 for 1.18.1. The enchantment used to generate such a long tooltip is from the mod "Fabric Enchantments" (Vanilla respiration should do the trick though).

In case anyone is wondering the cause of the issue, REI has its own tooltips it uses, and therefore u need an REI plugin to get this to work there. This mod could implement that without adding it as a requirement but I'm unsure how much work it would be. The REI wiki is a good resource if a tad hard on the eyes if I'm being totally candid

This should be fixed in 1.1.0

There is still an issue with the tooltip getting cut off on the right hand side of the screen:
