plate sometimes creates an "insert_node" operation of type image, and doesn't trigger renderLeaf for it

[yuvalshilo]

Description
Sometimes when the user paste image, the editor creates an operation of "insert_node" when node.type is "image".
but for a node of type "image", the renderLeaf function doesn't get triggered..

most of the times, when we paste image, it creates a new operation of "insert_node":

then everything works fine.

but sometimes, (and we have no idea when), it creates an operation of "insert_node" of type image:

when it does that, the renderLeaf function doesn't get triggered for that node.

1. when will it create this kind of node?
2. why does the renderLeaf function doesn't get triggered for that node?
