v5.16.0

• An improved media lightbox means no surprises as you progress through a gallery of images or videos, and you can pretend you’re really in a dark room by zooming to hide those pesky buttons.
• Fixed a bug where reacting to a message was tricky, because we put the picker off screen. That's now fixed, and you can 😮 to your ❤️ 's content.
• If you hover over the buttons while on a call, they stay visible instead of disappearing. Nothing hides from your eagle eye, not even these buttons!
