[FIXED] What is the maximum size for the postMessage method that enables inter-frame communication?

Issue

It's not clear from searching on Google and looking through documentation. What's the maximum length on a message sent via Window.postMessage (https://developer.mozilla.org/en-US/docs/Web/API/Window.postMessage)? We assume this varies by browser?

Solution

As a data point, the WebKit implementation (used by Safari and Chrome) doesn't currently enforce any limits (other than those imposed by running out of memory).
