Created attachment 192997 [details] vertAnchorWeird.pdf OK - MSO is extremely weird about how vertical alignment happens against the paragraph (aka "line"). I'm not actually sure we want to fix this, but at least I'll document it. This is different for compat15, but still, umm, strange. The attached PDF has 6 pages as seen by Word 2019: -page 1: compat14, anchored to LINE, outside/bottom. (huh?) -page 2: compat14, anchored to LINE, centered. (really - that is centered MS?) -page 3: compat14, anchored to LINE, inside/top. (umm, looks centered to me...) and the next three pages are repeated, but as compat15 Of course, LO doesn't look anything like any of those...

Created attachment 192999 [details] 160068_centerLine_compat15.docx: Page 5 example, round-tripped by MSO2019 This was the most interesting example. See bug 160049 for so ideas about what is happening here. The "above paragraph space" in the paragraph properties is likely coming into play here.
Just chiming in to say that this behavior is present in Version: 24.8.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: a2265e8faa099d9652efd12392c2877c2df1d1eb CPU threads: 8; OS: Windows 10.0 Build 19045; UI render: default; VCL: win Locale: en-US (en_US); UI: en-US Calc: threaded as well as Version: 24.2.1.2 (X86_64) / LibreOffice Community Build ID: db4def46b0453cc22e2d0305797cf981b68ef5ac CPU threads: 8; OS: Windows 10.0 Build 19045; UI render: default; VCL: win Locale: en-US (en_US); UI: en-US Calc: threaded It's very strange.
