This is to let you know that there is something funny about the width of text blocks of TidBITS issue "#1443: Blackmail spam, iPhone Camera app zoom tips, 5K displays disappearing, all about the Markup tools in macOS", as shown below in the screenshot. The formatting issue happens in Mail app on the iPhone (iOS 12.1), but not in Mail.app on the MacBook Pro. I tried but could not identify the anomalous HTML code.
