Merged
Conversation
Wait for all paginated report items to render via flushSync and useLayoutEffect before capturing DOM for Word export, so multi-page reports include content beyond the first preview page. Co-authored-by: Cursor <cursoragent@cursor.com>

Pull request overview
This PR fixes Word export for multi-page reports by temporarily rendering the full set of report items (instead of only the currently paginated preview page) and waiting for the DOM to finish rendering before capturing HTML for doc generation.
Changes:
- Added a Word-export-only render path (
wordExportItems/displayReportItems) to render all report items for capture. - Introduced a DOM-ready synchronization mechanism using
flushSync+useLayoutEffect+requestAnimationFrame. - Refactored Word export flow to wait for full render (and ECharts init) before calling HTML-to-Docx conversion.
