-// We're using a polyfill for the upcoming CSS4 `:focus-visible` pseudo-selector.
-// This allows us to not have to override default accessibility driven focus
-// styles for buttons in the case when a user clicks on a button. This also
-// gives better visibility to individuals who navigate with the keyboard.
-// Note: This was previously `:focus-ring` using the `wcig-focus-ring` library,
-// but that one was deprecated in favor of `focus-visible`.
