1753949 - Explicitly disable dFPI for cross-origin wpt tests in html/cross-origin-opener-policy

Status: RESOLVED FIXED

Description

[Tim Huang[:timhuang]]

We need to disable dFPI for some wpt tests in html/cross-origin-opener-policy because they are relying on the broadcast channel to send data across different top-level windows with distinct origins. The broadcast channel is partitioned in this case, so we need to disable dFPI in order to make these tests work.

These tests include

• html/cross-origin-opener-policy/historical/popup-same-origin-unsafe-allow-outgoing-with-cross-origin.https.html
• html/cross-origin-opener-policy/historical/popup-same-site-unsafe-allow-outgoing-with-cross-origin.https.html

Attachment: Bug 1753949 - Disable dFPI for cross-origin-opener-policy WPTs. r?annevk

The test framework of cross-origin-opener-policy WPTs is based on
broadcast channels to send data across origins. This behavior will fail
when dFPI is enabled because we partition broadcast channels.

This patch disables dFPI for the WPTs that will send data across origins
by using broadcast channels.
