If a browser window has a Web Inspector open in a separate window, closing the browser window causes a crash.
STR:
- Open a browser window.
- Open the Web Inspector (Command+Option+I, Inspect Element, etc.)
- If the Web Inspector is docked to the browser window, click the "Detach into separate window" button in the Inspector toolbar to move it to its own window.
- Close the browser window.
Result: crash
Notes:
I've only been able to reproduce this on macOS 14 Sonoma (I'm on 14.8.1). Another machine on 15.7.1 does not crash.
I also saw this issue a while back in Safari Technology Preview. I haven't seen it in recent builds, but I'm not sure if it was ever actually fixed, or it's just because STP moved to only supporting macOS 15 and up.
