I read the paragraph styles of my paragraphs, and their block settings are as expected. The separator has a single block, and the body has no blocks. This is a straight-up bug, but in Apple’s code (during rendering). That’s the problem with rarely-used/mentioned classes: not only does barely anyone knows how to use them, sometimes the creators didn’t do enough testing. Since the bug is on Apple’s side (# 30968328), I can’t fix it and I’m stuck. The only idea in mind, besides giving up, is to create a 1x1 table.
