Tooltips not showing up when hovering over entities in the world

When I hover over entities in the world, I see no tooltips. My “Draw World Tooltips” option is enabled, and ive looked around and cant find out why. Any help would be much appriciated.

To clarify, this is the kind of tooltip im talking about

Are you sure the entities you are looking at actually have world tooltips?

yes, stuff like wiremod i remember having lots of them

Wiremod uses custom world tips now.

I cant see any, ever, though.
