Cause (Documented platform behavior): Refs are only valid against the current snapshot; resolution failure throws this message.
Fix status: documented_behavior

- Retrying the same ref without a new snapshot

Proposed fix: [Playwright MCP] 'Ref <ref> not found in the current page snapshot. Try capturing new snapshot.' — stale aria ref after navigation/DOM change
Recommended action: Take a fresh browser_snapshot and use the new ref (don't reuse refs across navigations/re-renders).
Option: Take a fresh browser_snapshot and use the new ref (don't reuse refs across navigations/re-renders). [evidence: official_recommended_action]
Applies when: browser_click/type/etc. with a ref from an earlier snapshot
Steps:
1. Call browser_snapshot
2. Pick the element's new ref
3. Retry the action
Expected: The error no longer appears.
