I remember. But back then I thought, that would only be a problem with one
line.

No, I have not yet found the workaround. Only in the stripped example there's
one column. Actually I get the problem in my two-column layout and there I
can't remove the span="all".

Can you think of a different workaround?
Can you guess when your new pagebreaking mechanism will be finished?
Do you have a hint where I can find this special (and buggy) page break
handling?

This is very probably another manifestation of bug #46322:
https://issues.apache.org/bugzilla/show_bug.cgi?id=46322

The bug is triggered even if the previous blocks also span the whole page. The
fact that you didn't explicitly specify span="all" on the previous block makes
the code believe that there is a change in the spanning, which triggers some
special (and buggy) page break handling.

You found the workaround already. Hopefully it doesn't upset your whole tool
chain. That's all I can say for now :-\
