     'text-indent' and 'border-collapse' values, so that we can verify that
     the table does indeed use the initial value for these properties, rather
     than simply inheriting. -->

/* These styles come from the default `table` styling here:
 *  https://html.spec.whatwg.org/multipage/rendering.html#tables-2
 * We can't check for these values directly, because they may be
 * serialized slightly differently when read from the computed style.
 * So, for each property here, we apply it to a "reference" div and then
 * read back the computed value, and we validate that a table element
 * has that same computed value by default. */
