Arabic support for variable fonts

The latest adobe apps that support variable fonts doesn't support Arabic as the letters takes the isolated form without the basic Arabic features like initial, medial and final and so on 

Is there any intention to support Arabic in the future ?

Here is an example of the error

the word عربي looks great in the first line because it's not a variable font

The bottom version is a variable font the letters is all isolated  ع ر ب ي and it should look like the upper version
