On AliExpress, a dispute chat window was designed for portrait mode only and its elements scaled solely based on the WIDTH of the viewport. In a roughly 1920×1000 window on my desktop, the title bar used a giant font and took up over ½ the screen height, and the bottom textbox filled up the rest but still failed to show up in full. The website did not even change when zooming out, so I needed to resize the viewport just to read the messages.
Unfortunately, I didn’t take a screenshot (and I could not find any online), and I cannot access this chat interface after resolving the dispute. I suppose the page was supposed to be embedded in a chatbox in the corner of another website, or only shown fullscreen to mobile users, but I was somehow linked to it nonetheless.
