     runs on `input` — so nothing sized it until you typed, while the placeholder wraps to
     two lines on a phone and had its second line sliced through the middle. min-height also
     beats the inline height autoGrow sets, so typing a short message cannot shrink it back
     below this. 2.9em = two lines at line-height 1.45; 22px = the 10px padding either side
