Smoother chat videos
- WhatsApp and Telegram videos keep their wallpaper all the way down to the message box, even when the chat is still short.
- Typing a long message in a chat video: the box grows up in one piece and stays on the bottom of the screen.
- No more thin lines where the chat meets the message box in the video preview.
- Telegram's soft fade sits above the message box, like in the app.
- A paused video preview updates straight away when the watermark changes.
