A Reddit video sat in the wrong box until you pressed play, for two reasons that looked like one. The renderer put only `aspect-ratio` on the `<video>`. A video with no data has a natural size of 300x150, and WebKit sizes a replaced element from that rather than from the ratio, so a portrait video got a squat landscape box and kept it until playback supplied real dimensions. Chromium stretch-fits instead and gets it right, which is why this only showed on Safari. A video's size before its data arrives is its poster's, so one with no poster of its own now gets an empty SVG of the right shape as a stand-in: a data URI, so it costs no request. Measured in both engines across portrait, landscape, square and small. And Reddit's videos with sound had no poster to be sized by, because `fromRedditVideo` attached the still from `preview.images` to the MP4 branch alone. The still belongs to the video, not to the format it is served in, so every post with sound showed an empty box where a silent one showed a frame. It now goes on both.
