Details
As described in this post, enabling cross-origin isolation should give us more fine-grained and consistent timings from
performance.now()
,performance.mark()
, etc.I didn't see a good place to add tests, but let me know if there is one, and I'd be happy to add it. The main outcome is that we want
window.crossOriginIsolated
to be true in the browser.Does this PR introduce a breaking change?
