## 🕷 Tracking Issue (optional)

Start with the linked CodeSandbox reproduction and the ComboBox component behavior described in the issue. Reproduce repeated selections with the component offset from the top, then inspect the relevant ComboBox entry point and the proposed overflow-anchor behavior. Done means selecting items repeatedly no longer scrolls the page to the top.
