static-cms: RangeError: Maximum call stack size exceeded

Describe the bug

I was typing up a new blog post, and apparently triggered a stack overflow.

To Reproduce

It is likely related to my custom preview component. https://github.com/fimion/alex-party/blob/872523065ce8859d5d3cf7c4fee7c2bb8f8473bb/src/pages/admin.astro#L36-L67
