Inbox emails with dark (black) backgrounds do not display correctly making text unreadable [LINUX]

When viewing incoming emails that have a dark (black in this example) background the black background is not displayed, this making the white text invisible on the white background.

Example … emails sent from the BBC re iPlayer content. These work normally in other email browsers (same account).

The text can be seen if you swap to ‘dark mode’ or highlight the text.
