Discovered a bit of a temporary work around... I installed the latest Safari Technology Preview (Release 154 (Safari 16.0, WebKit 17615.1.6.2)) and ran the following commands to update Orion's WebInspectorUI.framework
with a newer version from the Safari TP app:
mv /Applications/Orion.app/Contents/Frameworks/WebInspectorUI.framework /Applications/Orion.app/Contents/Frameworks/WebInspectorUI_backup.framework
cp -r /Applications/Safari\ Technology\ Preview.app/Contents/Frameworks/WebInspectorUI.framework /Applications/Orion.app/Contents/Frameworks
Version from Safari TP 154: 17615.1.6.2
Version in Orion 0.99.120.1-beta: 17614.1.20
Version numbers of WebInspectorUI.framework can be found inside the framework: Versions/Current/Resources/Info.plist
under key CFBundleVersion
.
This resolved the issue for me, on macOS 12.6 (21G115).
