did you file a bug with apple?

No, but I've submitted feedback on Safari including this link:

I'm not really impressed with Apple when it comes to reporting a bug. After I
hit submit, the page froze, and I'm not sure my feedback was submitted.

Feedback submitted on second attempt. I hit the X in the location bar and hit
the submit button again.
