Sync web-platform-tests PR 10456 into mozilla-central (this bug is closed when the sync is complete). PR: https://github.com/w3c/web-platform-tests/pull/10456 Details from upstream follow. Alex Moshchuk <alexmos@chromium.org> wrote: > Reland: Use PostTask to schedule cross-process postMessage forwarding. > > Changes from original attempt at https://crrev.com/c/999182: > - fix flakiness in two additional ChromeOS login tests > - fix CSP WPT tests to not depend on ordering between iframe's onload > and postMessage - see https://crbug.com/832319. > > Previously, we sent the IPC to forward a cross-process postMessage > immediately. This caused a behavioral difference from the > same-process case where the postMessage is always scheduled. Namely, > in a scenario like this: > > frame.postMessage(...); > doSomethingThatSendsIPCsToFrame(frame); > > the IPCs from JS following the postMessage would've been ordered > incorrectly, causing |frame| to see their side effects after the > postMessage dispatch in the cross-process case, whereas they would be > seen before the postMessage dispatch in the same-process case. One > example of this is frame.focus(), and another is a frame element > onload event (dispatched via FrameHostMsg_DispatchLoad) arriving after > a postMessage dispatched from an inline script while the frame was > still loading. > > To resolve these ordering concerns, this CL changes cross-process > postMessage to do a PostTask on the sender side before sending the > message to the browser process. This improves the current state of > the world, but does not yet achieve a perfect match for the IPC > ordering in the same-process case - see discussion on the bug. > > Bug: 828529 > Change-Id: I62a627c501526d09900be4f5bd2c899acf4d1e07 > Reviewed-on: https://chromium-review.googlesource.com/999182 > Reviewed-by: Xiyuan Xia <xiyuan@chromium.org> > Reviewed-by: Daniel Cheng <dcheng@chromium.org> > Commit-Queue: Alex Moshchuk <alexmos@chromium.org> > Cr-Commit-Position: refs/heads/master@{#550284} > Reviewed-on: https://chromium-review.googlesource.com/1011287 > WPT-Export-Revision: 55cade9ddbf9ec079503bb9f66c62320e2972ff3
