[TextLayer] Immediately set the padding, rather than checking if it's empty, in `expandTextDivs`

In practice it's extremely rare[1] for the padding to be zero in *all* components, hence it seems better to just set it directly rather than creating a temporary variable and checking for the "no padding"-case.
