test_mso2024.pdf: how it looks in MS Word 2024 (with SimSun font available)
I found several examples where the document's spacing became worse instead of
better (compared to MS Word) after
26.2 commit e78940b7de0e3913a0b77c1874e162d8a63c6eb7

tdf#129808 sw: Extend leading for CJK fonts in DOC/DOCX files
Reviewed-on: https://gerrit.libreoffice.org/c/core/+/190297
Steps to reproduce:
1.) open test.doc (attachment 45722 from bug 36315) in LO (contains some use of
SimSun font)
Notice that the text now is spread out so that it almost fills the entire page.
In MS Word 2024, it ends much early - doesn't come near the bottom of the page.
[Note that Google says that Microsoft started shipping the SimSun font with
Windows Vista. (I also tested on Windows XP/Word 2010 which did not have that
font installed. In that case it looked like the current LO - but after I
installed the SimSun font on that system, then it matched how it was shown in
MS Word 2019.)]
Not name-blaming this regression as this is clearly an implementation-chasing
exercise. I'm just documenting this to provide a place to report specific
documents that apparently exhibit some additional constraints.
