Click event bug demo

Quick radio button switching is no longer possible in iOS 15 (it works fine in previous versions.)

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?

Bug explanation with sound

This one is really annoying — added somewhat better explanation video with sound.
