This directory contains tests that require disabling the automatic process isolation of web platform test origins. That isolation is usually useful for increased test coverage, but in some tests it interferes with the system under test. See https://crbug.com/1073181 for background.

This is separate from the not-site-per-process virtual test suite, which disables site isolation entirely. Tests running under this virtual test suite benefit from site isolation (e.g. isolating not-web-platform.test from web-platform.test). They just do not get automatic origin isolation (e.g. isolating web-platform.test from www.web-platform.test).
