@codebytere I don’t think this has been fixed correctly (or if it has then it seems to have regressed). This is still an issue in Electron
23.1.0. I tested it on Electron19.1.8and it is working perfectly but fails on Electron23.1.0. Let me know if you’d like me to put together a gist?hey - yeah, i need to manually open a backport to 20. I can try to do it tomorrow 😃
@rafaelpimpa sweet - so here: https://github.com/electron/electron/compare/v20.0.0-nightly.20220517...v20.0.0-nightly.20220518
i’d guess the Chromium roll - we’ll keep looking from here, thank you 🙇🏻♀️
In the end, I managed to get it working using Electron version 23.2.1 on my Mac running 13.3.1 using this gist: https://gist.github.com/rafaelpimpa/17afc65be515f3a1aec6256cb69f069d
@rafaelpimpa got a fix up!
