I don‘t know when this happend, but Jetbrains added an autocomplete to the terminal input of Webstorm. So when you start typing a common command, some sort of select box opens and it catches your keyboard focus, so you cannot keep typing. You also cannot type in the select, you have to use the arrow keys or the mouse–or hit ESC to close it. And then you type the next letter AND IT OPENS AGAIN. WHY?! I am typing faster than selecting some entries in a dropdownish thing. I really hate this.
