lpd-au has just created a new issue for https://github.com/w3c/csswg-drafts: == [cssom-view] visual viewport sometimes reportedly cannot fully scale out to layout viewport == I have an older site with a viewport meta tag like this: `<meta name="viewport" content="width=1024">`. When fully pinch-zoomed out on a mobile device (and upon first loading), I would expect the visual viewport to be at minimum 1024 CSS pixels wide, matching the layout viewport. However, depending on the mobile device, that isn't always the case. Here's my simplified test case: https://output.jsbin.com/xesolop And here's the widths reported by the Visual Viewport API: ``` PIXEL 6 PRO Firefox: - Portrait: 1024 - Landscape: 1024 Chrome - Portrait: 1024 - Landscape: 1023.9999389648438 PIXEL 7 Firefox - Portrait: 1024 - Landscape: 1023.9833374023438 Chrome - Portrait: 1023.9998779296875 - Landscape: 1024 GALAXY S23 Firefox: - Portrait: 1024 - Landscape: 1024 Chrome - Portrait: 1024 - Landscape: 1024 ``` Is reporting 1023.9 (when fully pinch-zoomed out) expected/allowed behaviour? From my point of view, it's undesirable behaviour since it complicates detecting when the user has either pinch-zoomed in or refreshed the page whilst zoomed (`visualViewport.width < 1024`). Thanks!
