Open the bugdoc, go to the end of the "Cannot press Delete here"
paragraph, press delete, layout hangs.
The trouble seems to be that this creates a doc model where multiple
multi-page floating tables are anchored to the same paragraph, which is
not something the layout supports. We explicitly avoid this at import
time from DOCX since commit 01ad8ec4bb (sw
floattable: fix lost tables around a floating table from DOCX,
2023-06-05), but there was no mechanism to prevent the UI creating the
same unsupported doc model.
Fix the problem by extending SwWrtShell::DelRight() to prevent joining 2
paragraphs in the unwanted case, interesting Word doesn't allow deleting
at the end of that paragraph, either.
Regression from commit 693ad3aadb
(tdf#120262 sw floattable, legacy: go outside body only for page frame
vert pos, 2023-07-31), which restricted the amount of cases where some
weird legacy behavior was performed, so good to keep that side as-is.
