Notice

• If </script> is intended as a closing tag but does not appear at the beginning of a line, syntax highlighting will also break (though single-line <script> tags are not affected but semicolon is required):

  <!-- bad -->
  <script lang="ts" context="module">
    const a = 1;</script>
  
  <!-- good -->
  <script lang="ts" context="module">
    const a = 1
  </script>
  <script lang="ts" context="module">const a = 1;</script>

• If </script> appears as a string and at the beginning of a line, syntax highlighting will break:

  <script lang="ts" context="module">
    const a = `
  </script> <- break
  `;
  </script>

  However, since </script> as a string currently is also not supported by Svelte, so this issue has no impact.
