Yeah I just did, it still reproes.
To use the latest WebKit you go to https://webkit.org/build-archives/, download the WebKit build you want, run sudo xattr -r -d com.apple.quarantine
on all the files (they're not signed), then run the run-webkit-archive
script that comes in the zip file.
I also tried launching Orion with that script, but I could still repro the bug, so I guess it didn't quite work, maybe because Orion already has its own version of WebKit, so setting the DYDL_*
environment variables isn't enough.
Would be cool to have a /Applications/Safari.app/Contents/MacOS/SafariForWebKitDevelopment
equivalent for Orion.
