Paste content to lexical editor with CORS-protected images will create invalid document in database

Describe the Bug

Pasting CORS-protected images into the Lexical editor on a collection with drafts enabled causes unhandled errors in PayloadCMS.

Link to the code that reproduces this issue

https://github.com/llaz00/payload-paste-image-bug

Reproduction Steps

1. Create a project with a collection that has a rich text field using the Lexical editor.
2. Enable drafts.
3. Try to paste content containing CORS-protected images (e.g., I used this article: https://www.xataka.com/moviles/llevamos-anos-sufriendo-llamadas-spam-operadores-miraban-uno-ellos-fin-va-a-hacer-algo).
4. A CORS error appears in the browser console; the Media dialog does not open, but the post can still be saved as a draft. This results in an invalid document in the database.
5. Attempting to update any other field of the document using payload.update returns a ValidationError because the upload block ID within the rich text field is invalid.
