Behavior

• Positioned relative to its anchor (pointingTo, or the element it's rendered in) using fixed coordinates, and follows it while open.
• Flips to the other side when the preferred one has no room, slides along the cross-axis to stay within the viewport, and shrinks to what's left.
• Escape closes it while the focus is inside it.
• With autohide it's modal: it takes the focus when it opens, Tab cycles inside it, and Escape (wherever the focus is) or a click outside closes it. That click doesn't reach what's under the pointer.
• Closing with the focus inside gives the focus back to the anchor.
