Pasted file path prefix customize

Use case or problem

my folder like

$ tree .

├── assets/
├── posts/

I have published post from posts to web, assets folder will stay in webroot like

even though I use "attachmentFolderPath": "/assets",, pasted image path always remove /, get ![](assets/foo.png), wihch cause image access 404

Proposed solution
