--- Comment #2 from Darin Senneff <darin.senneff at gmail.com> ---
Issue still present in iOS 18's developer beta #2, despite the iOS 18 beta's release notes including the following text:

"Fixed updating 'aria-describedby' text after the targeted element changes its subtree."

Safari + VoiceOver's handling of accessible descriptions continues to be a huge support gap. Oftentimes, an accessible description is used to provide error or status messages, or instructions, which may change after initial page load. Being unable to rely on this consistently means developers can't reliably provide certain information to screen reader users in Safari browsers.
