    <thetext>Consider merging https://chromium.googlesource.com/chromium/blink/+/5117d5329f6cdf071dfec25d9026a105070142b6

This improves page load time of The Economist by 41% (3.4s -&gt; 2.0s) on
my z620 workstation.

I believe the change in the inspector/styles/device-metrics-fit-window.html expectations is a progression.
The div being measured has a fixed width of 1024 and there is a zoom on the page.
It looks to me like there was a rounding error previously.

    <thetext>Nice. I don&apos;t like the &quot;fixed&quot; terminology though; too easily confused with fixed position.</thetext>
