In `@packages/extension/src/webview/components/MermaidPreviewPanel.tsx`:
- Around line 328-337: Add a unit test for MermaidPreviewPanel that verifies the
new dismiss path: render the panel with exportStatus set to a non-"working"
state (e.g., {type: "success"} and {type: "error"}) and assert the close button
(element with class statusCloseButton or aria-label "Close export status
message") is visible for those states but not when exportStatus.type ===
"working"; simulate a click on that close button and assert that the
setExportStatus mock is called with { type: "idle" } (use the existing test
harness/mock for setExportStatus to locate the prop passed into
MermaidPreviewPanel and reuse the alert/role-based selectors already present in
tests).
- Around line 324-326: The ARIA live-region currently forces aria-live="polite"
even when exportStatus.type === "error" which conflicts with role="alert";
update the JSX in MermaidPreviewPanel so aria-live is set to "assertive" (or
omitted) for error cases and keep aria-live="polite" only when role="status"
(i.e., exportStatus.type !== "error"), and ensure the dismiss/close button
(rendered when exportStatus.type !== "working") is focusable and wired to its
close handler; then add a unit/RTL test that renders MermaidPreviewPanel with
exportStatus non-working (e.g., "error" and a non-error case), asserts the aria
role/live values, clicks the dismiss button and verifies the close handler or UI
state change is invoked.

🧹 Nitpick | 🔵 Trivial | ⚡ Quick win
Add tests for the new dismiss path.
This introduces user-facing state transitions (show close button for success/error, hide for working, click resets to idle). The provided test context covers status/alert roles, but not this new close interaction. A focused test here would prevent regressions in exactly the thing this PR adds.

- Fix ARIA live region semantics: only set aria-live="polite" for non-alert status - Role="alert" already implies aria-live="assertive", setting aria-live="polite" contradicts this - Removes double-speaking issues on screen readers (VoiceOver iOS) - Dismiss button UI and functionality preserved All tests passing: 452/452 ✓
