Failed to resolve the relative background image url in css when there're (/) in it's parent paths.

[sapphi-red]

Describe the bug

It seems to fail to resolve the relative background image url in css when a component is located in a folder containing brackets.

A workaround is to wrap the url with double quotes:

.foo {
  background: url(./javascript.svg); /* before */
  background: url("./javascript.svg"); /* after */
}

This works in build.

The problem I've found is that the @ path won't resolve either, as of version 6.1.0

<=6.0.11

@lvzhenbo I'm not sure if that's caused by the same root problem. Would you create a minimal reproduction for it?

After trying to reproduce it, I realized that the problem I was having was related to using tailwindcssv3
