Locally, with r274641, we end up with three frames >1s, with 15.69s spent in layout between them. This is massively worse than page load in Chrome or Firefox.

I cannot reproduce us being massively slower with a recent macOS beta. It's clearly slower than Chrome, but only by ~1 second until the page is fully rendered.

Followed up on Radar until we decide whether it's a WebKit or a Safari issue.
