…nt.postMessage The fire messageerror and Dispatch message steps already run inside a task on |destination|'s client message queue, so wrapping them in an additional Queue a task on |targetClient|'s responsible event loop is redundant (both queues target the destination client's event loop) and potentially incorrect (the outer client message queue task source is superseded by the inner DOM manipulation task source). This reverts the Client.postMessage changes from w3c#1836, per @asutherland's post-merge feedback on that PR. The Clients.get and Clients.claim changes from w3c#1836 are unaffected.
