There is no built-in way to confirm whether an uploaded favicon is being correctly served, cached, and indexed across major browsers and search engines, so a favicon can appear correct in one engine. At the same time, a related issue in another goes unnoticed for an extended period.

Suggested Enhancement: Provide a favicon diagnostic view in Site customization that reports the favicon's live status (file accessibility, MIME type, dimensions) and known indexing state across major search engines.

Customer Benefit: Users get earlier, self-service confirmation that a favicon is configured correctly, without manually checking multiple browsers and search engines over time.
