Fix(input_label_visible) should not trigger when clipped 0,0,0,0 - different behavior in FF vs Chrome

[philljenkins]

The Carbon Tab list does not trigger this rule in Chrome, but does in Firefox:

• Rule ID: input_label_visible:
  • Needs review
  • Reason ID: potential_no_label The input element does not have an associated visible label
  • An input element must have an associated visible label

The SVG button is clipped 0,0,0,0 in this Carbon tab list buttons, so this rule should not be triggered:
See
https://react.carbondesignsystem.com/iframe.html?args=&id=components-tabs--default&viewMode=story

<button
    title="Remove Dashboard tab"
    class="cds--visually-hidden cds--tabs__nav-item--close-icon--selected"
    aria-hidden="true"
    tabindex="-1"
    type="button">

In Chrome, the style is
cds--tabs__nav-item--close--hidden {
clip: rect(0, 0, 0, 0);

In Firefox, the style is also:
.cds--tabs__nav-item--close--hidden {
clip: rect(0,0,0,0);

but, Firefox is warning:

clip is deprecated by W3C standards.
