Cancelling a queued message now avoids accidentally turning its text into a slash command
What
When you cancel a message that was queued up in the composer, Claude Code puts its text back for you to edit. That text now goes through a cleanup step that normalizes things like image placeholders. If that cleanup happens to make the text start with a / (which would make Claude Code treat it as a slash command) but the original raw text didn't start with /, Claude Code now keeps the original raw text instead.
Why
This prevents a queued message from being misinterpreted as a slash command just because of how its text was cleaned up, which could otherwise trigger unintended command behavior when a cancelled message is restored.
