Issue Management Verification Checklist

Run these checks with a real drawing loaded through viewer.documents.open(...).

• Add issue is disabled until the Viewer is ready and the drawing is open.
• Starting an issue marker calls viewer.tools.set(...) with action SHAPE_ELLIPSE and visible issue styling.
• The UI waits for viewer.annotations.on("created", ...) before opening the task editor.
• The task stores the created annotation guid or uniqueId.
• Saving an issue creates a task linked to the captured annotation ID and clears the active tool.
• Canceling a new unsaved issue deletes the captured annotation with viewer.annotations.delete(...).
• Selecting a task calls viewer.annotations.select(...) with the linked annotation ID.
• Selecting an issue marker in Canvas opens the matching task in edit mode through viewer.annotations.on("selected", ...).
• Resolve/Reopen changes task status without deleting the marker.
• Unmount destroys the Viewer and removes annotation event listeners.
