Not a bug, but a feature!
Let's have structrure:
Header\r\rText\r\rSubheader\r\rText
And css:
h1 { margin: 2.5 em 0; } h2 { margin: 1.5 em 0; } p { margin: 1em 0; }
It would seem between paragraph and headings must be indented 2.5 + 1.5 = 4em,
but because of the collapse this is not happening and is indented 2.5 em just as much as you for the title.
It's great, would otherwise have to bother with
h1 { margin: 2.5 em 0; } h1 + h2 { margin-bottom: 1.5 em; } h1 + p { margin-bottom: 1em; }
