No - I can reproduce the problem in another browser This behaves correctly in Firefox and incorrectly in Safari and Chrome. See attached images. Steps to reproduce the problem: 1.Load data:text/html,<textarea cols="3" rows="3">XXXXXXXXXXXXX</textarea><style>textarea { overflow: hidden; }</style> in Safari. 2.You will see that 4 columns (+ almost a 5th one with just whitespace) are rendered Problem Description: This should render just 3 columns but instead overflow hidden (and clip) only hide the scrollbar but still reserves its space. This behaviour can also be seen in Chrome but NOT Firefox. I came across it as I believe this is the part of the cause of one of the failing tests as part of the scrollbar-width implementation. The ref test (https://wpt.live/css/css-scrollbars/textarea-scrollbar-width-none.html) relies on this behaviour being correct and it isn't. 1955122 1 lwarlow 2023-05-12 16:21:38 -0700 Pull request: https://github.com/WebKit/WebKit/pull/13832 1955137 2 ahmad.saleem792 2023-05-12 17:04:15 -0700 Isn't it same as bug 253310? If Yes, let me know I can mark other duplicate of this. 1955216 3 lwarlow 2023-05-13 01:34:34 -0700 They're related but not the same. This is about the space reserved for a scrollbar in situations where it shouldn't be. The other one is about the resize handle itself being hidden when scrollbars are hidden (using legacy CSS or scrollbar-width) 1955375 4 webkit-bug-importer 2023-05-15 01:43:04 -0700 <rdar://problem/109343502> 1955561 5 ews-feeder 2023-05-15 18:42:44 -0700 Committed 264095@main (9ae5f9cb52ff): <https://commits.webkit.org/264095@main> Reviewed commits have been landed.
