User interface bug: Redshift promotional banner cannot be closed

Redshift banner touting preview cluster option pops up every time I visit the page and cannot be closed.

Try new Amazon Redshift features in preview.Create preview cluster Create a cluster with preview features. Production use of the cluster is not supported. Use this cluster for testing only.

Console shows this error... [Report Only] Refused to apply inline style because it violates the following Content Security Policy directive: "style-src <URL> <URL>". Either the 'unsafe-inline' keyword, a hash ('sha256-XTOOWbMsh6dXtrIPLf0Ophom1MWWbAY0gwI/5MOfdY0='), or a nonce ('nonce-...') is required to enable inline execution. Note that hashes do not apply to event handlers, style attributes and javascript: navigations unless the 'unsafe-hashes' keyword is present.
