// the past (Ref: https://crbug.com/40361673, https://crbug.com/396998476).
//
// The significant difference is that this mode still relies on
// RenderFrameHostImpl::SendBeforeUnload() in for_legacy mode.
//
// This means both the control and enabled groups will adjust the
// common_params start time. This is more consistent than sky@'s original
// experiment and will show an improvement on metrics like FCP, but the
// improvement will look inflated because the denominator (i.e., how long the
// navigation was to begin with) was incorrectly too small. We think this
// could be fine as long as we don't use FCP or similar metrics based on the
// common_params start time to judge the size of the improvement.
//
// Using Navigation.Timeline.TotalExcludingBeforeUnload.Duration should give
// us a better picture of how much skipping the PostTask helps.

// When this mode is specified, the navigation will synchronously continue if
// it knows beforeunload handlers are not registered.
