The order followed is the order of CSS Fonts Level 3.

To remind that common ligatures should work for most languages, there are a few here:
Ligature state | Arabic script | Thai | Hanunóo | Buginese |

Notes | The Arabic example has both the order of diacritics which shows the ligature (actually getting them farther apart), on the left, and the order which is not programmed to ligate, on the right. The ligature appears on Chrome and IE10 (always, even when disabled), and never on Firefox.

Firefox on Windows forces the ligature, it’s undisableable, the others ignore it.

The test was flawed because most of these ligatures can be produced by three different tables: 'cjct' conjunct forms in Devanagari2 for Sanskrit (dev2{SAN }), 'pres' old pre-base substs in Devanagari (deva{SAN }, dev2{SAN }), and 'hlig' hist ligatures in Devanagari (dev2{dflt} dev2{GUJ ,SAN ,SAT } deva{dflt} deva{GUJ ,SAN ,SAT }). Given that I put the Sanskrit language tag, one of the two former features was applied, because in the first row of the table we could see ligatures, so it couldn’t be the
hlig lookup. In fact one triconsonant appears only in hlig, and the four-consonants don’t work. |

Maybe changing this from musc{dflt} to DFLT{dflt}, or adding DFLT{dflt} may help.
