// The chrome.runtime does not currently support transferables; it forces JSON serialization.
// See bug https://bugs.chromium.org/p/chromium/issues/detail?id=927134
//
// Regarding transferables, the postMessage doc states:
// If the ownership of an object is transferred, it becomes unusable (neutered)
// in the context it was sent from and becomes available only to the worker it was sent to.
//
// Even though Chrome is eventually JSON serializing the array buffer,
// using the transferable approach also sometimes causes it to throw:
// DOMException: Failed to execute 'postMessage' on 'Window': ArrayBuffer at index 0 is already neutered.
//
// See bug https://github.com/bvaughn/react-devtools-experimental/issues/25
//
// The Store has a fallback in place that parses the message as JSON if the type isn't an array.
// For now the simplest fix seems to be to not transfer the array.
// This will negatively impact performance on Firefox so it's unfortunate,
// but until we're able to fix the Chrome error mentioned above, it seems necessary.
