To try to reproduce. 1. Plug the iPad (landscape) to a mac. 2. Open amazon.com 3. Develop Menu -> Select iPad 4. Click on the top left icon for the device settings. 5. Choose Disable site-specific hacks 6. Go to https://www.amazon.com/Exclusive-Thrilling-Heroics-Firefly-Stainless/dp/B01GIJ88XC/ 7. Tap on the product image 8. A window appears on the right side with a blow up of the image and a blue grid on the original image 9. move the blue grid around Expected: The corresponding image on the right side is moving along. If I didn't misunderstand the bug, it would mean that this part can be removed. https://github.com/WebKit/WebKit/blob/8f07bf9963e1bf4e307fc0d68556df4b21d2e95d/Source/WebCore/page/Quirks.cpp#L526-L533 2056970 1 webkit-bug-importer 2024-09-02 02:50:00 -0700 <rdar://problem/135134914> 2056971 2 karlcow 2024-09-02 02:55:13 -0700 Notes: In the original bug report it says that the page should not scroll when moving the blue grid. hmm maybe I can reproduce on some images. 2056983 3 karlcow 2024-09-02 04:54:36 -0700 Interestingly, it seems that Amazon has a special case for iPad. In https://m.media-amazon.com/images/I/11e6YKvz8HL._RC|61ERslxmD0L.js,614OTpIBP-L.js,11QPSzcZzFL.js,21Tlkr4uAnL.js,31e-8pJy4aL.js_.js?AUIClients/DetailPageDesktopImageBlockMetaAsset&dKPSvb9N r = e.detailImageUrl, b = e.useHoverZoomIpad || 0, which is defined in the HTML inside a string var obj = jQuery.parseJSON(' here JSON to parse ') which includes: "useChildVideos": true, "useClickZoom": false, "useHoverZoom": true, "useHoverZoomIpad": false, I wonder if developers are puzzled by the behavior of the iPad. Maybe there's an opportunity for Outreach. The quirk is triggered for "magnifierLens". for example <div id="magnifierLens" style=" position: absolute; background-image: url(&quot;https://m.media-amazon.com/images/G/01/apparel/rcxgs/tile._CB483369110_.gif&quot;); cursor: pointer; width: 117px; height: 162px; left: 102px; top: 113px;"> </div> 2056984 4 karlcow 2024-09-02 04:54:57 -0700 All of this is handled by ``` ca = function() { function b(a) { var b = Math.round(Math.min(l.width(), q.rect.width / a)); a = Math.round(Math.min(l.height(), q.rect.height / a)); r.css({ width: b, height: a }); d = [b, a] } var c = this, d = [0, 0], n = (q.detailSize && q.detailSize[0] || 5E8) / y[2], f = (q.detailSize && q.detailSize[1] || 5E8) / y[3]; n = f > n ? f : n; a("#magnifierLens").remove(); var r = a("\x3cdiv id\x3d'magnifierLens' /\x3e").css({ position: "absolute" }); e.generalImageUrls.zoomLensBackground && r.css({ backgroundImage: "url(" + e.generalImageUrls.zoomLensBackground + ")" }); D.showMagnifierOnHover ? H(r) : r.css("cursor", "pointer"); c.updatePosition = function() { var a = [y[2] - d[0], y[3] - d[1]], b = 0 >= a[0] ? .5 : Math.max(0, Math.min(1, (v[0] - d[0] / 2 - y[0] - c.offset.left) / a[0])), n = 0 >= a[1] ? .5 : Math.max(0, Math.min(1, (v[1] - d[1] / 2 - y[1] - c.offset.top) / a[1])), f = y[0] + Math.round(b * a[0]); a = y[1] + Math.round(n * a[1]); r.get(0).style.left = f + "px"; r.get(0).style.top = a + "px"; return [b, n] }; c.destroy = function() { r.remove() }; c.offset = l.offsetParent().offset(); b(n); c.updatePosition(); r.appendTo(l.parent()); q.detailImage[0].complete || q.detailImage.load(function() { var a = q.detailImage.width() / y[2]; b(a); c.updatePosition() }) }; ```
