305369 2026-01-13 01:24:35 -0800 REGRESSION (Safari 26.x): CSS rules within @scope not applied to input and textarea 2026-03-18 04:03:50 -0700 1 1 1 Unclassified WebKit Forms Safari Technology Preview Mac (Apple Silicon) macOS 26 RESOLVED FIXED https://github.com/web-platform-tests/wpt/pull/58025 InRadar P2 Normal --- 1 nicolas m_dubet annevk cdumez koivisto lily_spiniolas morozov.roman.u webkit-bug-importer wenson_hsieh yukiito oldest_to_newest 2171371 0 477978 nicolas 2026-01-13 01:24:35 -0800 Created attachment 477978 Test sample that shows the unexpected behavior. It appears that there is not way to apply css rules to an input anymore when they are declared in a @scope, bounded or not. For the following snippet (see attachement) <style> @scope (.test) { input { border: blue solid 1rem; } } input { outline: red solid 1rem ; } </style> <input type="text" placeholder="Test Input"> Expected result: The input should show both blue border and red outline. Actual result: The input only show the blue border and the red outline is mssing. This behavior is not reproductible on pre-26 safari, but appears in all 26.2, tech preview and webkit archive. 2171602 1 webkit-bug-importer 2026-01-13 16:02:25 -0800 <rdar://problem/168101378> 2173432 2 m_dubet 2026-01-20 13:00:27 -0800 Pull request: https://github.com/WebKit/WebKit/pull/56921 2174627 3 ews-feeder 2026-01-23 16:09:01 -0800 Committed 306129@main (a6e8f5201887): <https://commits.webkit.org/306129@main> Reviewed commits have been landed.
