Created attachment 473021 [details] Testcase See test-case. When src is set on a disconnected image, the image seems to get loaded synchronously even though when loading=lazy is set Note chrome has a similar bug: https://issues.chromium.org/issues/375209498

To be clear, this is dependent on attribute ordering, and is not allowed by the spec.

Created attachment 473183 [details] testcase as html file Thanks Emilio, I can confirm this is happening on the latest versions of Safari. There is a load event on Safari event: load, target: [object HTMLImageElement] On the other hand I do not see the bug happening on Chrome. Google Chrome Canary 132.0.6825.0 6825.0

There must be a question of timing in the execution of that code, because if I do a step by step in the Web Inspector Sources tab. The image is not being loaded.
