As the same instance of a map is used in context and mutated directly, this leads to a situation where: - Calling WithMediaTypeKeyPrefix from parallel goroutines where the context was based on the same base context can trigger a panic. - A subcontext calling WithMediaTypeKeyPrefix changes the value for another context when they both originate from the same base context.
