Hello,
I can also confirm this is a normal occurrence on Windows while using
Chrome and Edge. Firefox, however, does not do this. It is a bit confusing
for new users of IPA as they will generally treat it as a login prompt,
although it doesn't do anything for them. I have been curious about this
prompt, but haven't had a chance to look into it yet.
This is a bug in Windows browsers based on Chrome engine. It is known
for years and Chrome developers refused to fix it.
One thing you can do is to follow a recipe in
https://bugzilla.redhat.com/show_bug.cgi?id=1309041
...
<Location "/ipa">
AuthType GSSAPI
AuthName "Kerberos Login"
BrowserMatch Windows gssapi-no-negotiate
...
Perhaps, we need to finally add this line to the default IPA
configuration as per https://pagure.io/freeipa/issue/5614

I see this on Windows 10 Home with Chrome 93.0.4577.82 (and older
versions).
I get two login prompts - the first is caused by a POST to
/ipa/session/json resulting in a 401.
The second is caused by a GET for /ipa/session/login_kerberos?_=<some
timestamp>.
Both responses have the WWW-Authenticate: Negotiate header.
I happen to have MIT Kerberos for Windows installed--that may or may not
be relevant. I've not (as far as I remember) configured Chrome to try to
use SPNEGO to talk to my IPA servers so this may not be relevant.
