I confirm it.
This problem is not general. Some mails do not get any problem. Another problem, the mouse cursor when hovering a link, does not change. It remains an arrow.
I've found this happens with any links that have target="_blank" in the <a> tag. When you try to click such a link, the following is output to the terminal: Can not adopt content from a different WebEngineProfile. I'm attaching a small mbox file I created to demonstrate this.
