Since a couple of months it doesn't work well. After the jump, the first line of the next paragraph has dropped away. One has to scroll a bit up to get it back.
I've tried to give the Read-On tag more space, but it doesn't help. What the Tag seems to do, is adding space in the text. Even when I have pre-added it myself. It also happens with a jpeg, if that is what comes next after the jump. The top of the picture will be cut off a bit.
You can see - I assume - the effect here, in the post that opens with (forgive me) Joan Rivers:
"Even the poorest or otherwise unobtrusive " has dropped from view, plus half of the next line . Quite irritating.
Perhaps there is something that I can add to the tag?
