pubsub: incorrect default value for PublishSettings LimitExceededBehavior

[minj131]

// FlowControlSettings controls flow control for messages while publishing or subscribing.
type FlowControlSettings struct {
	// MaxOutstandingMessages is the maximum number of bufered messages to be published.
	// If less than or equal to zero, this is disabled.
	MaxOutstandingMessages int

	// MaxOutstandingBytes is the maximum size of buffered messages to be published.
	// If less than or equal to zero, this is disabled.
	MaxOutstandingBytes int

	// LimitExceededBehavior configures the behavior when trying to publish
	// additional messages while the flow controller is full. The available options
	// include Block (default), Ignore (disable), and SignalError (publish
	// results will return an error).
	LimitExceededBehavior LimitExceededBehavior
}

As you can see in the docs, it says that the default behavior is to block but below it is set to ignore.

// DefaultPublishSettings holds the default values for topics' PublishSettings.
var DefaultPublishSettings = PublishSettings{
	DelayThreshold: 10 * time.Millisecond,
	CountThreshold: 100,
	ByteThreshold:  1e6,
	Timeout:        60 * time.Second,
	// By default, limit the bundler to 10 times the max message size. The number 10 is
	// chosen as a reasonable amount of messages in the worst case whilst still
	// capping the number to a low enough value to not OOM users.
	BufferedByteLimit: 10 * MaxPublishRequestBytes,
	FlowControlSettings: FlowControlSettings{
		MaxOutstandingMessages: 1000,
		MaxOutstandingBytes:    -1,
		LimitExceededBehavior:  FlowControlIgnore,
	},
}
