The demo tab says what the demo is

On a task that is ready with a demo, the first line of the result list used to read "▶ Demo" and looked like a play button, though it is a tab that switches between the demo and the changed files. It now says "Demo video" or "Demo artifact", without the triangle. And when the picked demo or file lies below the visible part of the card, a click on its line now scrolls it into view instead of seeming to do nothing.
