Inline keyboard buttons become unresponsive with the new "menu transition" animation that appears when the menu is edited after tapping on a button.
This happens for all inline keyboard menu that are edited once a button is tapped, @BotFather is just an example of bot that does it.

Once you are back, all buttons can be tapped.
