- [X] `imports/cyto/editor.tsx` ✅ Commit [`a323238`](https://github.com/deep-foundation/deepcase/commit/a323238cc5f0b5ffd17b78d6835fe0a58b04d651)

• Locate the click event handler for the 'X' button.
• Trace back how the ID is passed to the deletion function in this event handler.
• If the ID is found to be undefined, identify where and why this is happening.
• Add checks or safeguards to ensure the ID is properly set and passed, or fix any bugs or issues that are causing the ID to be lost or not set correctly.
