Comparators do not update their state when blocking or unblocking a chest with a block on top

I found this bug where comparators dont output any signal from a chest, when the chest has a block on top. I'm not sure if it's intended, but I thought I might as well post it. It allows for a cool clock like in the third screenshot, However the clock creates major lag spikes on servers after 1 minute or so, more lag than it should.
Since I don't seem to be able to upload screenshots, I uploaded them to imgur:
