Response is reread after cancelling tool confirmation

[jrieken]

Testing #249657

• enable voiceover and screen reader
• install GH MCP
• prompt: "Add a comment saying "Testing..." to Test: chatUserActionRequired accessibilty signal #249657. Use #github"
• cancel the tool confimation
• 🐛 the response is read again, it would have expected something like "cancelled, not continuing"

Interesting - this would happen if hitting cancel focuses the chat response element erroneously.
