Description
Prevent mutating cookies on incoming HTTP requests if the cookie name is in the scrubbers denylist.
Cookies like
token=...were replaced withAnnotatedValuebecause a shallow reference of the request information was held by the client. A deep copy is introduced so scrubbing does not interfere with Litestar, and in particular does not breakJWTCookieAuth. Other HTTP integrations already create a deep copy. For instance,sentry-python/sentry_sdk/integrations/starlette.py
