This service is required by the "PermissionOnDeviceNotificationPredictions"
feature which is enabled by default in https://crbug.com/1350956. It uses a
Google backend service as described at https://go.dev/solutions/google/chrome.
This change removes the usage of PredictionBasedPermissionUiSelector, which
triggered this dependency, along with related startup complexity that was added
to support the optimization/prediction service in the M106 update.
Send a FrameDetached message from CefFrameHostImpl::Detach before closing
the RenderFrame connection to avoid an immediate reconnect attempt by the
renderer.
When BFCache is disabled the intentionally detached frame will never be
reconnected. When BFCache is enabled the intentionally detached frame will
be reconnected via CefFrameImpl::OnWasShown if/when it exits the cache.
Run with "--vmodule=frame_*=1 --enable-logging=stderr --no-sandbox" on the
command-line to see these log messages from both the browser and renderer
processes.
Disable BackForwardCache globally for the Alloy runtime so that
blink::RuntimeEnabledFeatures::BackForwardCacheEnables reports the
correct value in the renderer process.
DesktopWindowTreeHostWin ("Chrome_WidgetWin_0") focus needs to be set before
the associated call to WebContents::Focus. In the case of mouse click events,
this means ::SetFocus needs to be called explicitly. See updated comments in
CefBrowserPlatformDelegateNativeWin::SetFocus.
DesktopWindowTreeHostWin ("Chrome_WidgetWin_0") focus needs to be set
synchronously in response to the parent window WM_SETFOCUS message and
before the associated call to WebContents::Focus. See updated comments in
CefBrowserPlatformDelegateNativeWin::SetFocus.
Using a source_set here keeps the linker on Windows from discarding exported
compilation units that are not directly called from inside libcef_static.
This may also fix linker errors on Linux due to CEF's use of an intermediate
static library (see https://crbug.com/1319006#c2).
