Description

If I create three blocks on a page and make the first and third set to
span="all", a page break will be added. This pattern will continue for as many
alternating blocks as I include.

I need to create a heading that SPANS two columns, followed by some text IN
columns, repeated. It works fine for the first two fo:blocks, but after that it
begins added page breaks in weird places. Also, this behavior will occur even
with column-count="1" instead of "2". The problem starts with the second
<fo:block span="all"> element.

I tried to fix this by using multiple region-body elements, but it failed. Code
below...
