Describe the bug

Description When using the TailwindAdvancedEditor sample from the Novel repo, enabling TaskList or BulletList causes the placeholder text to render twice or overlap.

Selecting Task List shows two placeholders: one inside the task item and one at the root.

Selecting Bullet List or Numbered List makes two placeholders overlap visually.

This behavior occurs in the official TailwindAdvancedEditor example without any modifications.
