Perspective - Numeric Input Value Component BUG?

This might help...

In the linked example I created a 'MyCSS.css' file that is imported into the theme I'm using. If you add

input::-webkit-outer-spin-button,
input::-webkit-inner-spin-button {
  -webkit-appearance: none;
  padding: 0px 0px;
  margin: 0;
}

to your css file, all of up/down (spinner) arrows should be hidden. Y
