Thanks for sharing your report, it's frustrating to see things like this break in minor patch updates. Small tip for GitHub Gist: set the file format to markdown (give it a .md extension) so that the markdown will be rendered and won't require horizontal scrolling :)
The report says it broke when updating from macOS 15 to 26, so not a minor patch update. I'm a bit surprised no one noticed this earlier though, since 26 has been out since September and in beta since June.
