For target="_blank" to work, sandbox attribute requires the allow-popups-to-escape-sandbox option in iframe/embedded formats

[derya-meral]

When we embedded our calendar on SquareSpace, we were having trouble opening Action Network links from our event details. The page would open, but AN's RSVP button would be broken. We realized that we needed to add allow-popups-to-escape-sandbox to the sandbox attribute for target="_blank" to work properly. That seems to have fixed it.

Thank you for this project!
