This has basically been fixed in 6.3 thanks to bug 125719's exporting fix.

However, MSWord 2016 and 2010 show bold on the output from 6.1 too. (Perhaps it would act differently if supplemental language support is installed? I only have US defaults set.)

arabicRT61.rtf: round-tripped by LO 6.1. In MSWord, the first paragraph is bold.

It is still outstanding in 7.2+ that this round-tripped file has no bold paragraph in LibreOffice. However, it opens in Word 2016, 2003, and 2010 with the first paragraph in bold.

NEEDINFO because I want to confirm that MS Word setup for an Arabic user also shows it as bold. (That requires some extra packages installed, and I can't easily do that anymore.)
