font-size:8pt; not getting converted to <w:sz w:val="8"/> in ooxml.
If font-size is given as small,x-large,etc. it gets converted.
You'd expect it to get converted as w:val=16 since the measurement is in half points. https://github.com/plutext/docx4j/blob/master/docx4j-core/src/main/java/org/docx4j/model/properties/run/FontSize.java#L123
