So…what are they supposed to be? I'm only seeing incredibly blurry partial shapes…

Also different forums seem to have different new post indicator outlines now (from the same set that was gone through when that feature was implemented). Site Help and Bug Reports as well as the Department of Creativity have the minimal outline, while Scriptorium has what was until recently the common.

Aaand now Scriptorium has it too. Did I seriously catch a code change between opening posts sequentially in two adjacent tabs?
