Button doesnt work properly on a second click

I’ve faced a problem when I click on the “Press me” button (1) and then select the first block (2) in the “menu”, then when I click on the button again (3), the screen moves up, without opening the menu.

How to fix it? When you click on the button for a first time (1) it works properly but after another interaction it stucks (3).
