Overlay API for Custom Visuals – allow pop-ups outside the iframe


When developing **custom visuals** we often need to display menus,
rich tooltips or dialogs that don’t fit inside the visual’s
rectangle. Today everything is rendered inside an `<iframe>` with
`overflow:hidden`, so content is clipped when the user resizes the
object.

We request an **Overlay / Popup API** that lets a custom visual
render content over the entire canvas, following the same UI
behavior as native visuals (slicer dropdown, calendar, etc.).

Minimum requirements:
1. Host method such as `displayOverlay(htmlElement, options)`.
2. Z-index managed by the host to avoid stacking conflicts.
3. Auto-close when clicking outside or switching pages.
4. Works in Desktop, Service and mobile.

Benefits:
* User experience identical to native visuals.
* Saves dashboard space.

* Enables advanced tooltips, in-place editors, wizards, etc.

Thank you for considering this feature – it would unlock many
scenarios for the custom-visual community.
