What Is Popover=Hint?

- The `popover="hint"` attribute in HTML allows opening a hint popover without closing other popovers in the stack.
- This is useful for tooltips or preview cards, like profile previews on Twitter or Facebook.
- Three types of popovers exist: `auto`, `manual`, and `hint`, each with different behaviors regarding light dismiss and closing other popovers.
- A demo shows how a `hint` popover can stay open while an `auto` popover remains active, though clicking the `hint` popover may close the `auto` one.
- JavaScript event listeners are needed to manage hover and keyboard interactions for `hint` popovers.
- Experimental `interestfor` API enables declarative hover/focus-based popovers without JavaScript, currently behind a flag in Chrome Canary.
- `popover="hint"` and `interestfor` simplify building layered UI elements like tooltips and previews.
