Created attachment 440354 [details] Click event bug demo Quick radio button switching is no longer possible in iOS 15 (it works fine in previous versions.) https://codepen.io/otdaymobilu/pen/YzQoxVd Steps to reproduce: 1. Tap the first item. 2. Fast-tap the third item. 3. Tap the second item after any time. The third item is selected instead of the last clicked item (see attached video). Are there ways to solve this?
