Hi Karl. Yes.

No. I just installed Safari Tech Preview on Sonoma after your reply.

Right. The bug isn't about log spam.

There appears to be a "sweet spot" on the page where the log errors come in fast and furious. I could attach a spindump, but it's probably better if you can reproduce. I now have more precise steps:

1. Open https://www.espn.com
2. Scroll down the page until you see the aforementioned log errors
3. Find the nearest video, start playing it, and pause during the video advertisement
4. If the log errors aren't coming in super fast, scroll the page a little until you find the "sweet spot"
5. Leave the web inspector open and see the CPU usage grow in Activity Monitor
6. Type some commands into the console (doesn't matter what, document.querySelector or whatever)

When the log errors are appearing fast enough, and the CPU usage is high enough, the web inspector UI becomes completely hung, no longer responding to key presses or mouse clicks.
