Description Per Arne Vollan 2023-08-08 05:37:10 PDT

After 266255@main, a Web process is prewarmed on provisional load instead of when the main frame load has finished. This is a page load time progression on most iOS devices, except for the low end ones. For these devices, we should still be prewarming when the main frame load has finished. The change in 266255@main is also neutral on macOS, so we can also keep the original behavior there.
