3) What is expected to happen in LibreOffice Writer via the Terminal:

cd ~/Desktop && wget https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/281053/+attachment/2417117/+files/math_newline_issue.tar.gz && file-roller -h math_newline_issue.tar.gz && cd math_newline_issue && lowriter -nologo math_newline_issue.odt

is no upside down question marks are presented in the Math formulas.

4) What happens is the upside down question marks are present erroneously due to "newline" command. If "newline" is preceded or followed by some characters (as +, -, =, which are often needed), some error marks "¿" are obtained, and perhaps only a single line if displayed (it depends on the character and its relative position to "newline"). Examples :

a+b_ij = newline = c+d # single line; error mark
a+b_ij newline = c+d # two lines; missing "="; error mark
a+b_ij newline + c+d # correct behaviour !! The "+" sign does fine after newline...
a+b_ij + newline c+d # ... but not before: single line, error mark here
a+b_ij = newline c+d # single line, error mark. The "=" sign does bad whether after or before newline
