Some browsers, like Chromium 80+ or Safari 14+, will
transfer focus to a selected element like a text input
and therefore style the border of such element according
to an user agent stylesheet rule, such as:
:focus {outline: -webkit-focus-ring-color auto 1px;} .
So, we deliberately trigger such focus with the focus()
method in the reference file.

/*
When a text input element is focused in Firefox
82+, then the caret becomes visible and blinking and
it is painted with the ::selected's color which is
the green color in this case. We therefore counter,
neutralize this by resetting the caret's color to the
background color.
