(Harfbuzz problem? or original font was created with specific quirks of old LibreOffice in mind?)

Khaled: thought you might be interested in this one since it concerns fonts (and potentially Harfbuzz)

The font has a weird ligatures feature that breaks cursive connections, disabling ligatures gives the same output as previous version of LibreOffice (where ligatures were disabled by default for Latin script).

Ligatures are supposed to be enabled by default, so this is a font bug. LibreOffice is now rendering the font as designed.
