See bug 61594 for the context, this concrete situation is one where the intention is clearly a multi-page table, not a floating one. When there is a page break (or section break: next page) after such a table, that effectively disables any kind of wrapping, so in that case importing the table as a multi-page one is the correct thing to do (till the mentioned feature is not implemented).
Miklos Vajna committed a patch related to this issue.
It has been pushed to "master":
tdf#107773 DOC import: consider page breaks for multi-page floattables
It will be available in 5.4.0.
The patch should be included in the daily builds available at
http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More
information about daily builds can be found at:
Affected users are encouraged to test the fix and report feedback.

Compare OO, LO, master with MSO
Can't say why MSO has A1-3 on 1st page while Lo has A1-4 on 1st page.
Is it part of this bug or some other issue?
