What exactly is a "Dynamic Category"?
When looking at a Category page, look in the top right corner and you will see 3 buttons that changes the way the Category page looks to you (Classic Categories, Category Exhibition, and Dynamic Category)
Dynamic Categories have the template Bigcat built-into it.
Sadly, it looks like there is no special coding for Redirected pages when in 'Dynamic Category' mode - each item has the exact same css codes, unlike the 'Classic Category' mode which has special css for redirected pages. :(
Okay, so yeah it seems you're screwed, but you may have a case for saying redirects not-italicized is a bug, since the old category pages used to italicize redirects. If you can get FANDOM staff to fix this, then you can filter them.
Ack - it works great with the redirects in the dynamic category pages B U T it also applies this class to the redirects in the normal article / template pages as well where I want redirects to appear normal
So, I will have to remove the script :( and send in the bug report so that only the redirects in the dynamic category pages are affected! (hopefully)
