Bug: Word diff marks disappear on the new side while the editor is attached

<style>body { color-scheme: dark } body.light { color-scheme: light }</style>
<div id="scroller" style="height: 2000px; overflow: auto"><div id="diff"></div></div>

import { Virtualizer, VirtualizedFileDiff } from '@pierre/diffs';
import { Editor } from '@pierre/diffs/edit';

const PREFERRED_HIGHLIGHTER = 'highlights'; // or 'shiki-js'
const code = (changed: boolean) =>
  Array.from({ length: 30 }, (_, i) => `export function f${i}(x: number): number {\n  return ${changed && i === 15 ? 'y' : 'x'} + ${i};\n}`).join('\n') +
  `\nconst s = 'foo again${changed ? '170' : ''}';\n`;

const host = document.getElementById('diff')!;
const virtualizer = new Virtualizer();
virtualizer.setup(document.getElementById('scroller')!);
const view = new VirtualizedFileDiff(
  { theme: { dark: 'pierre-dark', light: 'pierre-light' }, preferredHighlighter: PREFERRED_HIGHLIGHTER, lineDiffType: 'word' },
  virtualizer,
);
view.render({ fileContainer: host, oldFile: { name: 'example.ts', contents: code(false) }, newFile: { name: 'example.ts', contents: code(true) } });

const marks = () => {
  const rows = [...host.shadowRoot!.querySelectorAll('[data-diff-span]')].map((mark) => mark.closest('[data-line-type]')?.getAttribute('data-line-type'));
  return `old side ${rows.filter((t) => t === 'change-deletion').length}, new side ${rows.filter((t) => t === 'change-addition').length}`;
};
const settle = () => new Promise((resolve) => setTimeout(resolve, 1000));

await settle();
console.log('1. rendered, read-only:', marks());
const editor = new Editor('file-diff');
const endEditing = editor.edit(view);
await settle();
console.log('2. editor attached:', marks());
document.body.classList.add('light'); // the page's color scheme turns light
await settle();
console.log('3. color scheme flipped while editing:', marks());
endEditing();
await settle();
console.log('4. editing ended:', marks());

highlights:
1. rendered, read-only: old side 2, new side 2
2. editor attached: old side 2, new side 0
3. color scheme flipped while editing: old side 2, new side 0
4. editing ended: old side 2, new side 2

shiki-js:
1. rendered, read-only: old side 2, new side 2
2. editor attached: old side 2, new side 2
3. color scheme flipped while editing: old side 2, new side 0
4. editing ended: old side 2, new side 2
