Drop interaction with onPaste function

**The question.**
I am working on the gallery plugin that can be populated by dropping images on one its element. I am also using the simple-image plugin that has a onPaste function that interacts with the drop function of my plugin : on dropping the images, they are added to the gallery plugin, but also as new image blocks.

Would there be a solution to prevent the simple-image plugin to be fired when the gallery is used?

Thanks

Start by reproducing the interaction between the gallery plugin's drop handling and the simple-image plugin's onPaste function. Trace both plugin entry points to determine why one drop creates both a gallery image and a new image block. Done means dropping images into the gallery no longer triggers the simple-image behavior, while normal simple-image paste or drop behavior remains intact.
