Conjuncts of 'ल' & 'श' not working when paragraph language set to 'Marathi'

[abhi-deshpande]

When the paragraph language is set to 'Marathi', the conjuncts of letter 'ल' and 'श' are not working. Conjuncts of other letters are working properly. Also, I tried Zero Width Joiner to render half forms of letters, but they are not working. The same thing worked for 'Hindi', though. The problem occurs for both the Jaini and Jaini Purva.

I am using the font in LibreOffice 6.0.7.3
Linux Mint 19.3
