Well, this screenshot is the mobile version. Tapping anywhere in a textbox should bring the focus and start typing. All having extra lines does is make it more likely that the starting insertion point is a line or two below the start.
Even on desktop, I’m not aware of any text box behavior where you need to click on the correct line to bring the focus to the box.
Procrastinator.
Okay, but seriously: “Thief”. Why reimplement it if it’s already available in the language?
