I believe I mentioned this before the redesign where you fixed that but unfortunately with the redesign this problem is back. In some cases where you have a long comment as the last one you are not able to read it as the overflow button is obstructing the view. I’ve attached a screenshot. Maybe this could be handled in another way, like making the button invisible as you hit the last comment.
Also and this is more like a feature: make spoilers per default hidden and only readable when clicking a button or something like that, to avoid reading to much. I actually did that more than once because I read something and then saw the Spoiler tagline above.
