Details

I'm trying to write single-file-components with view, behaviour and style in one file.

Expected Behavior

I should be able to put arbitrary valid CSS in the style block.

Actual Behavior

Most CSS is fine, but seemingly backslash seems to cause problems.

Steps to Reproduce

Insert the following into a Marko file.

style.scss {
  .foo {
    grid: "left right" / 3fr 7fr;
  }
}
