can not insert images into editor from subfolders

i post this as an issue on github, is it exists or i am doing something wrong?

--------------------------------------
I think this is a bug in inserting images using summernote (default editor) for opencart version 2.2.0,
i checked demo version (2.0.0.1b) currently installed on demo.opencart.com, but there is no such issue, but in version 2.2.0.0 if i want to inserting image from subfolder into the editor, it redirect me to that image (open it in browser) instead of inserting image into editor, if i select an image from root, it works but if i want to select image from subdirectory or navigate into subolder and return up to the root, clicking on image cause to navigate to that image (javascript event not fired or not attached to the images)

install version 2.2.0.0 and got to product edit page ad try to insert image from subfolder to the editor, you will see this issue.
