Underwater Skill Icons Misleading

For some reason, the skills you can't use underwater have a big water drop over waves overlaid on them. They also still have the little red x over the water drop in the upper right, so at least there's that indicator, but a big water symbol on a skill makes me think it's usable.

Was this iconography mis-applied? Or is it intended to convey "must be out of water to use?" The latter just is not intuitive (for me).

I don't know if this is new with this patch or I just didn't notice it before, as I've had no reason to rework my underwater skills for a very long time.
