This implementation only calls scrollIntoView if getPageElementByIndex returns an element, and otherwise returns false without changing scroll. When page virtualization is enabled, off‑screen pages are often not mounted in the DOM, so getPageElementByIndex will return null even for valid pages; in that case scrollToPage cannot bring the page into view at all. This makes the new public API fail for any page outside the mounted window. Consider using the same approach as other navigation helpers (e.g., scroll to the computed y‑position and/or wait for mount) so virtualized pages can be reached.
