See the attached document. It's nominally a floating table, but it's wide enough that no actual wrapping is performed. It would be better to import that as a normal table, so when it has enough content, it can flow to the next page.
Miklos Vajna committed a patch related to this issue.
It has been pushed to "master":
tdf#109063 DOCX import: consider wrap space for multi-page floattables
It will be available in 6.0.0.
The patch should be included in the daily builds available at
http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More
