We'll create fresh WordPress site with WP FastClick installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Why does the delay exist?
According to Google:
…mobile browsers will wait approximately 300ms from the time that you tap the button to fire the click event. The reason for this is that the browser is waiting to see if you are actually performing a double tap.
The aim is to make your application/website feel less laggy and more responsive while avoiding any interference with your current logic.
