Safari 15.5 embedded content slow to load

As part of the release of Safari 15.5, there seems to be an issue with Safari being able to load embedded content on some websites. One example is the US State Department’s site for reporting a lost or stolen passport:


This site has embedded content and Safari is very slow to load that site. The behavior seems to be tied to the Hide IP address from trackers setting in Safari’s privacy settings:

With that setting enabled, slow website loading:

With that setting disabled, normal website loading:

    I reported this a couple of hours ago to Apple via Feedback Assistant. Please add & duplicate FB10021550.

    FYI, this is affecting many high-profile public websites like http://www.cnn.com, http://www.yahoo.com, etc… and it even affected one of our internal corporate sites because a graphic object was hosted on a slightly different domain (that we own & control).

    The ’embedded resources’ that failed to load are fairly innocuous such as page analytics, graphics, javascript libraries, and even WOFF2 fonts hosted on other known & trusted domains like google. Without access to some of these, websites can be completely unusable.

    I don’t see a problem with the example site in mobile Safari on iOS 15.5 with “Hide IP address from trackers“ enabled.

    Can someone test this with the “Limit IP Address Tracking” enabled / disabled in System Preferences > Network? Specifically, try this with BOTH of the ‘hide’ options enabled (Safari Privacy and Network Prefs), and with one or both disabled?

    Is there a way to disable the “Hide IP address from trackers” feature in a .plist?

    I can’t reproduce this with Safari 15.5 on macOS 12.4. The sample page loads in 4.5 to 5 seconds, same as it does in Chrome. In case it matters, in System Preferences > Network, “Limit IP Address Tracking” is checked.

    Opening Safari’s DevTools and using its Network pane may give you more information about what’s happening.
