Drag and Drop image from adobe Illustrator extension to server/Desktop is not working on MAC OSX

[sargamj35545226]

Hello,

I created a HTML5 extension for Adobe Illustrator, on extension I am displaying images from local disk. But when  trying to drag drop image from extension to desktop or on server, image is not getting dropped. (For ex. If dragging image from extension to google image search image is not getting dropped.  On debugging dropbox at I found that, file object of image is created and added into dragged data store object on dragstart event but at drop location, on drop event File object of image is not there). I am not understanding why file object of image is deleted after dragStart event complete.same scenario working fine on Windows.

code to display Image on extension:

also tried by adding attribute "draggable=true"

Illustrator CC version : CC2019

Mac OSX: 10.14.6

attached Video of use case.

can you please help with this problem!

Thanks & Regards
