Universal SSL for IDN not issuing due to being flagged

Hi, I bought an IDN (Internationalized domain name) and attached it to Cloudflare but the Universal SSL isn't issuing so I cant use subdomains outside of the LE Cert issued on cf pages for the root domain, CF says its flagged as a "potential risk" by Virustotal, one Google search away shows this seems to be an issue for IDN domains and needs to be fixed by support manually
