A custom domain on my Static Web App has been stuck in "Deleting" status for several hours

Question

A custom domain on my Static Web App has been stuck in "Deleting" status for several hours

Radu Chiriţă 20

I created a CNAME record at my external DNS provider (cPanel). The record propagated correctly and is still in place. Requests reach Azure and return the standard Azure "404 Web Site not found" page, which confirms DNS resolution is working.
I added the custom domain in the Azure portal using CNAME validation. Validation failed with the message: "An unknown error has occurred while adding your custom domain. Please try again later."
I retried validation several times over several hours with no change.
I deleted the domain entry from the portal. It has remained in "Deleting" status ever since.
I ran the CLI delete: The command showed "InProgress" and then returned: "Operation returned an invalid status 'OK'". The domain was not removed.
Current state, from az staticwebapp hostname list:

What I have already checked:

No resource locks on the Static Web App or on the resource group.
The DNS CNAME record is present and correct, and has not been modified or removed.
The domain has never been bound to any other Azure resource.

No, the domain still appears "deleting" and I cannot try to add it.
