Reviewed by Alan Baradlay.

Return up-to-date values when script asks for metrics when using
API (like getBoundingClientRect()) that needs to measure layout, rather
than waiting for the step in "update the rendering" [1].

This matches the gecko implementation whereas chromium uses a
"whitelist" solution, needing to adjust many call sites.
