Query for TXT record returns CNAME of the domain

[leonid-shevtsov]

expected result, from Cloudflare:

>dig TXT @1.1.1.1 leonid.shevtsov.me

;; ANSWER SECTION:
leonid.shevtsov.me.     900     IN      TXT     "spf snip"
leonid.shevtsov.me.     900     IN      TXT     "google snip"

actual result from unbound:

>dig TXT @127.0.0.1 leonid.shevtsov.me

;; ANSWER SECTION:
leonid.shevtsov.me.     10      IN      CNAME   cname.vercel-dns.com.

The zone uses Hover for DNS, so both TXT records and the CNAME are defined there. There is a CNAME for this subdomain because it is hosted on Vercel. This is a typical setup.

I've never seen it affect TXT record resolution before. Looks like a bug, or at least behavior that doesn't match the norm. For example, Google site verification works, and mxtoolbox finds the SPF record. But unbound cannot find either TXT record.
