Images get dark overlay

[joachimcarrein]

Some of my emails are shown with "hidden" images. They seem to get a dark overlay as well:

I don't get that in all mails though.
If required, I can forward it to you.

As far as I can see, there is an image overlay of the newspaper on items where it's behind a paywall, and these are shown bigger thus blocking the image behind.

Just for reference, this is the part without the darkmode on

Thanks for letting me know, I'm going to look into it in the next days
