I am planning for this to be shipped in 121, providing no other regressions/bugs are found in the mean time. 1. I'll close this bug when I land the enabling patch (Bug 1860729), planning for early next week. 2. This is expected but we may not do this correctly yet, [we fail the WPT along with Chromium](https://wpt.fyi/results/html/semantics/embedded-content/the-iframe-element/iframe-loading-lazy-load-event.html). (This is not blocking shipping it.) 3. Yes, scripting needs to be enabled for both images and iframes.

I am planning for this to be shipped in 121, providing no other regressions/bugs are found in the mean time. 1. This bug is remaining mostly untouched, see the enabling bug - Bug 1860729. 2.
