How do I whitelist external content for e-mails in Thunderbird?

To protect my privacy and prevent tracking pixels, I had blocked external content in Thunderbird. Previously, a bar appeared above the mail in Thunderbird indicating that external media was hidden in these messages - and on the right I could then open a drop-down menu to add domains to the whitelist.
For a few weeks/months now (currently Thunderbird 141.0 x64), however, only ‘To protect your privacy, Thunderbird has blocked remote content in this message.’ appears here, followed by an X to close the notification.

I have added alerts@gg.deals and gg.deals to the whitelist - if they are other domains, I can no longer identify them in the new view. 'Allow remote content in messages' is activated in the settings.
What can I do to see the external content again? Some messages, especially those from familiar senders, are really unpleasant to process.

One other thing you can do is verify the sender domain is really what's listed
View >> Headers >> All

You'll see the entire path the message took to get to you, just back track until you find the sender server, and verify the html links further down of the images linked. Actually, an easier way to verify the linked image(s) domains would be to view the message in plaintext. If you scroll down, you should see the URL of the images
