Bug: table-toolbar and link-toolbar elements are duplicated in the DOM

[iamdabe]

Describe the bug:
The table-toolbar and link-toolbar elements are being duplicated in the DOM during editor usage. Additionally, styles for these elements are injected at the root level and impact global styles unintentionally.

Expected behavior:

• Only one instance of each toolbar element should exist in the DOM at any time.
• Styles for toolbar elements should be properly scoped to avoid interfering with root/global styles.

Steps to reproduce:

1. Open the Markdown Editor and trigger actions involving the table-toolbar and link-toolbar.
2. Inspect the DOM and observe duplication of these elements.
3. Review root DOM for style leakage related to toolbar styling.

Suggested fix:

• Ensure toolbar elements are not re-rendered or duplicated.
• Refactor styling logic to scope CSS for toolbars to avoid global application.

Additional context:
This affects editing experience and can cause layout/style conflicts when used in larger projects.
