-/**
- * Scroll SpreadsheetDocument to make a cell visible using arrow keys.
- * Uses native platform scroll — keeps headers, data, and scrollbar synchronized.
- *
- * How it works:
- * 1. Check target cell visibility via Playwright boundingBox (page-level coords).
- * 2. Click a fully-visible cell via page.mouse.click through the mxlCurrBody overlay.
- *    This is the same native click that clickSpreadsheetCell uses — it gives keyboard
- *    focus to the spreadsheet and keeps headers/data/scrollbar in sync.
- *    (frame.locator().click() bypasses overlay → desyncs frozen headers;
- *     page.mouse.click() + frameEl.focus() doesn't transfer keyboard focus.)
- * 3. Press ArrowRight/ArrowLeft until the target cell is fully within the viewport.
- *
- * @param {Frame} frame - Playwright Frame containing the spreadsheet cells
- * @param {number} physRow - physical row (y attribute) in the frame
- * @param {number} physCol - physical column (x attribute) in the frame
