Deleting <blockquote> in Editor causes Preview Error: NotFoundError - Failed to execute 'removeChild'

[skyfoliage]

First, thank you for developing this highly appreciated editor!

I tried to embed SNS quote cards such as Twitter (X), Instagram, and Bluesky using <blockquote> and then <script> in the editor. The preview was able to show these cards, but when I deleted the <blockquote> tag above the <script>, an error occurred.

NotFoundError: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.

I think that when I delete the <blockquote> in the editor, it affects the DOM tree, but it does not update the Previewer's React tree accordingly.
It seems possible to address this with onChange in MDEditor, but I would like a more fundamental solution.
What is the best practice to avoid this error?
