Curious if there is any update on this. I am currently using a hand full of mouseover macros for my Shaman and am also having issues with #showtooltip both not updating icons AND not actually showing tooltips.
This is one example of my macros. It works fine with default/elvui bars but neuron does not update the image of the spell when mousing over a target, nor does it show the tooltip when I mouseover the spell. (It only shows the name of the macro)
