[2.8.4c] NEI Fluid display does not work correctly

[Belgabor]

The fluid output display for recipes with liquid output in NEI doesn't work correctly. For some recipe types it does not work at all, for some only the popup with the fluid name and amount doesn't show up.

The really odd part is that at some point it worked when I used the development version in my project, I have no idea what's going on :/
