'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:
* 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. */
