Hence, I am creating separate bug to track it.

Thanks!!! 1892853 1 karlcow 2022-08-21 18:47:31 -0700 I probably depends on Bug 219005 as the test 18 depends on it. ``` function test18() { let t = createAndAppendElement("div"); t.style.height = "100px"; t.style.width = "50px"; let helper = new ResizeTestHelper( "test18: an observation is fired when device-pixel-content-box is being " + "observed", [ { setup: observer => { observer.observe(t, {box: "device-pixel-content-box"}); }, notify: entries => { assert_equals(entries.length, 1, "1 pending notification"); assert_equals(entries[0].target, t, "target is t"); assert_equals(entries[0].contentRect.width, 50, "target width"); assert_equals(entries[0].contentRect.height, 100, "target height"); assert_equals(entries[0].contentBoxSize[0].inlineSize, 50, "target content-box inline size"); assert_equals(entries[0].contentBoxSize[0].blockSize, 100, "target content-box block size"); assert_equals(entries[0].borderBoxSize[0].inlineSize, 50, "target border-box inline size"); assert_equals(entries[0].borderBoxSize[0].blockSize, 100, "target border-box block size"); assert_equals(entries[0].devicePixelContentBoxSize[0].inlineSize, 50, "target device-pixel-content-box inline size"); assert_equals(entries[0].devicePixelContentBoxSize[0].blockSize, 100, "target device-pixel-content-box block size"); } }, ]); return helper.start(() => t.remove()); } ``` And test 19 also would depends on it: zoom + device-pixel-content-box (zoom is non-standard and not supported by Firefox, hence the test number differences) PS: <3 the typo "Web-copmat" 1892854 2 webkit-bug-importer 2022-08-21 18:47:41 -0700 <rdar://problem/98956336> 1892856 3 karlcow 2022-08-21 18:53:11 -0700 seeAlso https://developer.mozilla.org/en-US/docs/Web/API/ResizeObserverEntry/devicePixelContentBoxSize#browser_compatibility
