Weird Text Shadows on Google Reader in Firefox 3.1/3.5 Betas

firefox-beta-google-reader-text-shadow

Does any­body else get these? When you nav­i­gate to your labels or sub­scrip­tions using key­board short­cuts, the high­light­ed item in this modal win­dow thing has a text “shad­ow” or dupli­cate sit­ting ten pix­els over to the left. It’s been both­er­ing me for a while now and I can’t find any­body else talk­ing about it. I guess I’m sup­posed to file a bug?
