tdf#164901 sw inline heading: fix lost floating tables

Style separators inside floating tables resulted losing of
the floating tables. In this case, don't handle style separators,
as before commit 56588663a0.

Regression since commit 56588663a0
"tdf#131728 sw inline heading: fix DOCX paragraph layout interoperability".
