Blacklist Bug in Grid View

Stumbled into this one at random guys. As a matter of course I have 'MLP' in my blacklist for every site that supports filtering. One of the artists I follow occasionally does MLP content, and while Weasyl makes sure I never see it, here I get a big 'Content Warning' banner when using List view. Do note, that's not the bug. The bug happens when I swap over to Grid view. When in Grid view, the submission thumbnail is shown. No 'Content Warning' banner, no removal from the list, it's just sitting there in plain view. Made me think that my filters were broken, as I tend to view things in Grid by default.
