### Bug Description When opening a modal `Dialog` from inside a `Popover`, interacting with elements inside the modal dialog (such as clicking a button) triggers an outside-click handler on the popover, causing the popover to unexpectedly close. ### Steps to Reproduce 1. Click the **Open popover** button (at 4.1s). 2. Inside the open popover, click **Open dialog** (at 6.7s). 3. In the modal dialog that appears, click the **Or click me** button (at 12.2s). ### Expected Behavior Interacting with the contents of the modal dialog should not close the parent popover. ### Actual Behavior Clicking inside the modal dialog closes both the dialog and the popover. The popover DOM element (`[data-popup]`) is completely removed. ### Concrete Evidence - **Visual:** At frame 13.0s, both the dialog overlay and popover disappear unexpectedly. - **Console Log (13.5s):** `BUG confirmed: Popover [data-popup] is gone after clicking inside the Dialog` *Recorded with SceneRecap.*
