Details

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:87.0) Gecko/20100101 Firefox/87.0

Steps to reproduce:

Network Settings -> Configure Proxy Access to the Internet -> Manual proxy configuration -> set http proxy -> Enable DNS over HTTPS

Actual results:

https://www.dnsleaktest.com/results.html
shows my real DNS,
but if I enable "No proxy" shows Cloudflare DNS

Expected results:

In firefox 86.0 and lower "DNS over HTTPS" with "Manual proxy configuration" worked together

Pretty sure this is expected, but leaving Nihanth to confirm before making this report public. Cf. https://bugzilla.mozilla.org/show_bug.cgi?id=1576053#c3 / https://bugzilla.mozilla.org/show_bug.cgi?id=1546924 .

Sorry for taking so long to respond here. Gijs is right, this is a known issue, but what's surprising to me is the suggestion that this was "working" in 86.

Also, the test page linked in comment 0 doesn't seem to display anything for me with DoH enabled (no proxy).

In any case, I don't think this needs to be hidden.
