Created attachment 471188 [details] Example HTML demonstrating the issue Steps to reproduce: 1. Open the attached example HTML 2. Open the web inspector 3. Click the "Shadow?" checkbox 4. Click the link Expected results: "click shadow button" is not logged in the console Actual results: "click shadow button" is logged in the console The expected results occur for all desktop web browsers: Safari, Chrome, Firefox. Mobile Safari's behavior is inconsistent with those. Discussion: The pointerdown event on the link calls preventDefault and shows a modal dialog. The example HTML has two dialogs, one of which is chosen by the Shadow? checkbox. Each dialog has a button inside, but one button is inside the Shadow DOM and one not. When the button is not inside the Shadow DOM, it doesn't receive a click event as a result of clicking on the link. When the button is inside the Shadow DOM, it doesn't receive a click event on desktop either but does on iOS.

@Jeff - by any chance, if you know whether it is recent regression?

(In reply to Ahmad Saleem from comment #2) > @Jeff - by any chance, if you know whether it is recent regression? It's not. I can reproduce in the iOS 16.4 simulator.
