As of https://crrev.com/9e653328e3 the Views framework will apply the "always
on top" (WS_EX_TOPMOST) style by default to widgets created with TYPE_MENU. CEF
uses this type in CefWindowView::CreateWidget to support child windows that are
not clipped to the parent window bounds (currently indicated by returning a
parent window from CefWindowDelegate::GetParentWindow and setting |is_menu| to
true).
Not setting "always on top" shouldn't be a problem except in cases where some
other window is already "always on top" and the child CefWindow is expected to
overlay that window. For this reason any menus created using ShowMenu will
continue to have the "always on top" style.
Fixes the following error:

These tests expect the window's client area size to be (kWSize, kWSize). Use
::AdjustWindowRect to offset TestWindowDelegate's preferred size so that the
client area size is correct after the OS internally applies frame insets during
::CreateWindow.
To test: Run `ceftests.exe --gtest_filter=ViewsWindowTest.Window*`.
All tests should pass.
Tests for incomplete request behavior use a timeout to trigger CloseBrowser
and terminate the test case. Recent architectural changes in Chromium have
likely increased the minimum delay required to spin up a working browser
instance and initiate the request. Consequently we need to wait longer before
closing the browser.
To test:
Run `ceftests --gtest_filter=URLRequestTest.*Incomplete* --gtest_repeat=5`.
All test runs should succeed.
This restores the default site isolation mode for Chromium on desktop
platforms. Unit tests have been updated to reflect the new behavior
expectations.
Known behavior changes in CEF are as follows:
- A spare renderer process may be created on initial browser creation or cross-
origin navigation. This spare process may be used with a future cross-origin
navigation or discarded on application shutdown. As a result
CefRenderProcessHandler::OnRenderThreadCreated, which is called shortly after
renderer process creation, can no longer be used to reliably transfer state
for the currently in-progress navigation. Unit tests have been updated to use
the CreateBrowser/OnBeforePopup |extra_info| value for transferring test state
to CefRenderProcessHandler::OnBrowserCreated which will be called in the
correct/expected renderer process.
- Cross-origin navigations will again receive a new renderer process, as
expected. This behavior had briefly regressed in M78 due to the
ProcessSharingWithDefaultSiteInstances feature becoming enabled by default.
- Cross-origin navigations initiated by calling LoadURL in the renderer process
will now crash that process with "bad IPC message" reason
INVALID_INITIATOR_ORIGIN (213). This is a security feature implemented in
Chromium.
- A DevTools browser created using CefBrowserHost::ShowDevTools will receive
the same CefRenderProcessHandler::OnBrowserCreated |extra_info| value that was
set via CreateBrowser/OnBeforePopup for the parent browser.
This reverts commit 2cf916e6d5.

Requests from the PDF viewer are not associated with a CefBrowser. Consequently,
the InterceptedRequestHandler for those requests will register as an observer of
CefContext destruction. When the browser is closed the InterceptedRequestHandler
is destroyed and an async task is posted to remove/delete the observer on the UI
thread. If CefShutdown is then called the task may execute after shutdown has
started, in which case CONTEXT_STATE_VALID() will return false. We still need to
remove the observer in this case to avoid a use-after-free in
FinishShutdownOnUIThread.
