Unable to copy assets to dist folder during packaging

Describe the bug

1、This is a vue2 project, and I have a component like this

2、when I packaged, the image files can't copy to the dist folder, so my static web has some show question

3、when I pass img url props, the vite can't check it all and package to the dist folder.

I don't know if this is intentional (wanted me to put it in the public folder), or a bug
