account.live.com certificate

Attempting to visit https://account.live.com with applications that use glib-networking results in "Unacceptable TLS certificate"/G_TLS_CERTIFICATE_GENERIC_ERROR. Visiting https://account.live.com with Firefox/curl -iv https://account.live.com/openssl s_client -connect account.live.com:443 all work, so I suspect something is wrong with how this certificate is being verified in version 2.70.0 of glib-networking.

There's two easy ways to reproduce the issue on Fedora 35 (Fedora 34 does not have the error):

Reproducing error via epiphany/webkitgtk:

On Fedora 35 (w/ glib-networking-2.70.0-1.fc35.x86_64), install the epiphany web browser
Attempt to visit https://account.live.com using epiphany

Reproducing error via libsoup examples (get.c):

On Fedora 35 (w/ glib-networking-2.70.0-1.fc35.x86_64), compile libsoup
Run get.c example: ./get https://account.live.com

$ ./get https://account.live.com
Failed to send request: Unacceptable TLS certificate
