I’m just reverting the change – way too dangerous for the minimal benefit of “prevents accidental keypresses” in the field. It’s really really bad on iPad.
Edit: I am also much more interested in “prevent pop of keyboard on mobile” than “whoops I pressed a key on desktop”. And all my searching indicates that is hard and error prone.
I guess a lot of this is copying something to clipboard which for security reasons, I guess, is made very difficult.
