images in _draft post asset folder can't be accessed using markdown

[SeriesOfUnlikelyExplanations]

looking at https://hexo.io/docs/asset-folders.html section "Embedding an image using markdown". When I use the markdown syntax for a post in my _posts folder it works fine, but when I try to do the same in _drafts it doesn't work. It looks like the referenced image doesn't get any prepended root "localhost:4000/trail-and-sunset.jpg" and it throws an error "Cannot GET".

Is there a way to enable using prepend root and post asset folder for posts in my _draft folder?

My _config:
post_asset_folder: true
marked:
gfm: true
prependRoot: true
postAsset: true

好像是不能修改 permalink 配置，改了路径就出问题了

Can't you check if the file exists in _posts folder and if it doesn't, then use the _drafts folder?
