Open DevTools > Canvas 4. Click "Reload" button Actual results: After step 4, record-snapshot button does not displayed on snapshots-toolbar. And also reload-notice-button is not replaced to canvas-debugging-empty-notice-button. But if clicking clear-snapshots, canvas-debugging-empty-notice-button is displayed. Expected results: Is this behavior intentional? If this is not, record-snapshot button and canvas-debugging-empty-notice-button are displayed after step 4.
