Emails from specific senders very slow to mark as Read after being clicked on

For the last couple of months, when I click on a new email, it can take up to 30 seconds for its status to change to "Read". This only happens on emails from specific senders, primarily email@nl.npr.org and ng@email.nationalgeographic.com, and it's consistent. I have the same problem on two computers with independent Thunderbird installations, both running Windows 11. Any ideas or confirmations?

This is continuing to happen on Version 115.3.2 (64-bit). Does anyone have any ideas or similar issues?
