Quite a number of CNAME redirects you have there!
The resolved logs appear to be fine, e.g.:
Mar 28 11:30:27 castle systemd-resolved[73519]: Added positive unauthenticated
cache entry for standard.t-0009.t-msedge.net IN A 30s on enp4s0f0/INET/10.18.1.1
Mar 28 11:30:27 castle systemd-resolved[73519]: Added positive unauthenticated
cache entry for standard.t-0009.t-msedge.net IN A 30s on enp4s0f0/INET/10.18.1.1
And when I try to resolve your example hostname it only goes through 2 CNAMES:
$ host static-exp1.licdn.com
static-exp1.licdn.com is an alias for 2-01-2c3e-003d.cdx.cedexis.net.
2-01-2c3e-003d.cdx.cedexis.net is an alias for cs1404.wpc.epsiloncdn.net.
cs1404.wpc.epsiloncdn.net has address 152.199.24.163
cs1404.wpc.epsiloncdn.net has IPv6 address
2606:2800:21f:fedd:8b7a:88ab:fc7e:fa3b
Do you have a different example hostname that I can try to reproduce this with?

Bug description:
I am having issues loading certain websites such as linkedin.com and
portions of google sites including images.google.com, hotmail.com
login, etc. After looking through some logs and such I've determined
that resolved is not properly following CNAMEs to an IP address.
Querying the DNS server on my network directly for the info works
fine. Loading the sites from other computers on the network works
fine.
In the #systemd IRC channel I was directed to the following two issues:
https://github.com/systemd/systemd/pull/18892
https://github.com/systemd/systemd/pull/19009
System info:
Ubuntu 20.10
ii systemd 246.6-1ubuntu1.2 amd64 system and service manager
ii linux-generic 5.8.0.48.53 amd64 Complete Generic Linux kernel
