Distortion of Armenian letters

Libreoffice twists the Armenian letter ն in combination with letters վ and մ in Sylfaen and some other fonts (the first line in the attached screenshot). In Times New Roman (the second line) the letters are typed correctly.

Repro, but not with 3.5.0.

Might be the transition to HarfBuzz.

These are ligatures in these fonts, and LibreOffice is simply rendering the text as the font designer intended it. You can either disable the ligatures or use different fonts that satisfy your requirements.
