Created attachment 470688 [details] Screen recording Safari 17.4.1 (18618.1.15.111.8, 18618) and Safari Technology Preview 191 (Safari 17.4, WebKit 18619.1.6.3) on macOS 13.6.6 (22G630) Steps to reproduce: 1. Open https://www.justtherecipe.com 2. Scroll down to the bottom of the page 3. Open the Safari web inspector 4. Create a breakpoint for the "click" event 5. Command-click on Privacy Policy The debugger gets stuck. I can type characters in the console, but I can't press return. And many of the buttons in the web inspector don't work, such as step over and step into. Also, the web page goes blank. See the attached screen recording. The website renders all of the controls at the bottom in an HTML <canvas> element.

@Jeff - is it regression or it was happening prior to 17.4 as well?
