tdf#93441: Revert "Fix fdo#38884 Improve Up/Down movement in writer"

This reverts commit d58bea0ffa2a2fe79103ab7aa743aea63e27a0fd

it's really unclear to me what the original commit tries to
fix.
https://bugs.documentfoundation.org/show_bug.cgi?id=38884#c6
gives some information but the behaviour described there
is the same with or without the commit applied.
The discussion in https://gerrit.libreoffice.org/c/core/+/11500
doesn't give much information either.
