HSBC Malaysia is not resolving with DoH when using native IPv6

1.1.1.1 connection information

I am using Google Chrome with Cloudflare DoH, when I try to visit HSBC Malaysia website, I get a DNS_PROBE_FINISHED_NXDOMAIN error.

When I disabled DoH and just use normal Cloudflare DNS , I stop getting the error.
When I change the DoH provider to Google DNS, I stop getting the error.

More clues, it seems to be related to IPv6. Once I disabled native IPv6 from my ISP, then everything works.

Is there a problem with Cloudflare DoH over a native IPv6 connection?

More edit.

Strange, when I use Cloudflare DoH with Firefox, then the same website loads. This is the 1.1.1.1 connection information with Firefox. Edge Chromium behaves exactly the same as Chrome.
