I'm not sure it's ready to be turned on yet, but this is a bug to track for when it's ready.

With the dependencies for this bug now closed (200764, 203557, 207901, 208119), is there a good chance loading=lazy might be turned on by default soon?

It only applies in some weird situations (maybe the fake Page associated with SVG images or something).

It seems this patch enabled `IsSameSiteStrictEnforcementEnabled` instead of `LazyImageLoadingEnabled`. $ git show --pretty=oneline 30c67adc54a265473c4fd44bbab6702e9be4487a -- Source/WTF/Scripts/ at 11:39:12 30c67adc54a265473c4fd44bbab6702e9be4487a Enable lazy image loading by default https://bugs.webkit.org/show_bug.cgi?id=208094 diff --git Source/WTF/Scripts/Preferences/WebPreferencesExperimental.yaml Source/WTF/Scripts/Preferences/WebPreferencesExperimental.yaml index 0266e84653..d9e36c19ed 100644 --- Source/WTF/Scripts/Preferences/WebPreferencesExperimental.yaml +++ Source/WTF/Scripts/Preferences/WebPreferencesExperimental.yaml @@ -700,7 +700,7 @@ IsSameSiteStrictEnforcementEnabled: WebKitLegacy: default: false WebKit: - default: false + default: true WebCore: default: false Notice @@ -700,7 +700,7 @@ IsSameSiteStrictEnforcementEnabled:

You're right. The patches look correct. I wonder if this was a merge issue by commit-queue.

Seems like something that needs a manual commit!
