Nested selectors in @container queries causing an unhandled exception

[shadow-identity]

Hi,

I noticed that when I try to nest selectors inside of a @container block, magicString.remove throws an exception:

@container main (width > 50em) {
    parent-tag {
        width: 0;
    
        & child-tag {
            width: 10px;
        }
    }
}

end must be greater than start

In opposite, @media works without this problem.
if I change the CSS language to SCSS, everything works (but we use plain CSS with nesting).

My stack is:

• sveltekit 1.25.1 (svelte@4.2.1)(vite@4.4.11)) (upgrade to the v2 is my next task ;)
• magic-string: 0.30.4 is a sveltekit dependency.
