Issue with Pattern column

The pattern column is not working properly. When I went to submit a new pattern on this URL (https://wordpress.org/patterns/new-pattern/), I noticed that the column is not working correctly — it displays in a row-wise manner.

To check the issue, I created a pattern locally using the column block, and then I pasted the same pattern into the editor at https://wordpress.org/patterns/new-pattern/. However, the views look different in both cases. I am attaching a screenshot of my local setup and one from the WordPress.org pattern submission page for reference.

I also see a console error in the editor when trying to submit the new pattern.

Would you like help identifying the cause of the layout or console error?

Reproduce the discrepancy by creating a pattern with the column block locally, then pasting it into https://wordpress.org/patterns/new-pattern/. Compare the two layouts and inspect the editor's console error; the issue is done when the column layout matches and the reported console error is resolved.
