Created attachment 200757 [details] splitParaTopMargin.docx Steps to reproduce: 1.) open splitParaTopMargin.docx Look at page 2. This should be a continuation of the Heading 1 page style, but it obviously is very different as can be seen by the non-blue, non-bold, smaller text. This never worked. There was no page break at all in OOo 3.3. When the page break appeared in LO 4.3, then this issue could be observed. Note that our import of the DOC version of this file (attachment 200755 [details] from bug 166552) does NOT exhibit this problem.
Created attachment 202070 [details] forum-mso-en-3220_minimal.docx: minimized sample. This bug report became a bit more important because I just exposed it with my 25.8 fix for bug 166544. The fix looks pretty straight forward. In DomainMapper::lcl_startParagraphGroup(), capture the state of m_pImpl->m_bIsSplitPara and then don't force default paragraph style.
ooxmlexport4's testTdf81345_045Original also clearly shows this for columns. Fixed in 7.6 is the lost column break (bug 153592), but now the green "Section Heading" style is missing on the heading "Microsoft Visual Studio 2005".
