The regex on line 25 is overly permissive: .? uses an unescaped . (matches any character), and home-assistant.io is not escaped (the . matches any character). This can cause unintended matches/skips. Use a stricter pattern (escape dots, and use an explicit optional subdomain group), or reuse the safer domain allowlist regex already present below.

@copilot can you give me some examples where this might be falsely matched?

@mrdarrengriffin I've opened a new pull request, #43938, to work on those changes. Once the pull request is ready, I'll request review from you.
