Cause due to styles:
Type this for input:

input, input:before, input:after {
      -webkit-user-select: initial;
      -khtml-user-select: initial;
      -moz-user-select: initial;
      -ms-user-select: initial;

     }

I had this problem, I had it because of position: relative; at the parent block. You may have a different problem, but it's worth a try.
