Still using this deleted question of mine on other site to test the Roomba Turbo Charging, I found another glitch in the design.
Was really hard to come with the descriptive title so let me demonstrate in a short vid: http://www.youtube.com/watch?v=kViC26_OfUs
As you see, while the score correctly "reset" itself back the upvote icon doesn't restore itself and stays in the "off" state.
This does not happen when trying to upvote post I didn't upvote before: icon becomes active, then restores itself back to inactive as it should. This also doesn't happen on ordinary non-deleted answers where the vote is locked.
I'm pretty sure it's not related to the recent changes, those just made me find this glitch now. :)
