The parseFileStructureFromContent works wrong sometimes

[alexprey]

The following input of markup returns the wrong output for script blocks

<script>
const example = `
    <script>
    </script>
`;
</script>

I was browsing the Svelte issues and actually, this is not a bug:
sveltejs/svelte#5810

If a developer wants to put </script> in a string literal or comment, it has to be escaped.

The following code should be correct for svelte, but this parser failed there:

<Panel title="Basic tabs" shadow={true}>
  <Tabs bind:items={items}/>
  <br><br>
  <strong>Active tab:</strong> {activeTab1[0].title}
  <br>
  <br>

  <Code>
    {@html highlight(
      '<script> \n' +
      '   const items = [ \n' + 
      '     { title: "Tab 1", active: true }, \n' +
      '     { title: "Tab 2", active: false }, \n' +
      '     { title: "Tab 3", active: false }, \n' +
      '     { title: "Tab 4", active: false }, \n' +
      '   ]; \n' +
      '</script> \n\n' +
      '<Tabs bind:items={items} />')}
  </Code>
</Panel>

The test was added in test\unit\helpers\helpers.spec.js
