Importantly this seems to be related to the select being inside a shadowroot, I can't reproduce without it. 2203865 1 ap 2026-04-23 13:58:30 -0700 Thank you for the report! I can reproduce with Safari 26 on macOS 26, but not with Safari 18.6 on macOS Sequoia 15.6.1. 2203866 2 webkit-bug-importer 2026-04-23 13:58:36 -0700 <rdar://problem/175454476> 2206082 3 kiet.ho 2026-04-29 19:14:52 -0700 Pull request: https://github.com/WebKit/WebKit/pull/63942 2208639 4 ews-feeder 2026-05-07 10:58:33 -0700 Committed 312811@main (7d2bb1ed4f24): <https://commits.webkit.org/312811@main> Reviewed commits have been landed.

I checked and I think they're different bugs. This bug manifests if the <select> is positioned using CSS anchor positioning.
