Begin by reproducing the issue in the Chat Timeline with Text Bubbles enabled, sending an image before any text message on an iPhone 14 Pro or comparable iOS device. Trace the timeline's image-message rendering and profile-picture sizing, then verify that the picture is correctly sized in both the image-first and text-first cases.
