This fix #21950

💡 Background and solution

Safari's default padding hide input box in multiple selection.

/* user agent style sheet in Safari */
textarea, input[type="range"], input, input:matches([type="password"], [type="search"]) {
  ...
  padding-top: 0.2em;
  padding-right: 0.5em;
  padding-bottom: 0.3em;
  padding-left: 0.5em;
}

/* user agent style sheet in Chrome */
textarea, input[type="range"], input, input:matches([type="password"], [type="search"]) {
  ...
  padding-top: 1px;
  padding-right: 1px;
  padding-bottom: 1px;
  padding-left: 1px;
}

So I add padding: 1px to input to avoid search box is hidden by browser.
