Information about the relevant DOM source range. The array will always contain, in order: starting position (inclusive), ending position (exclusive), width of the opening tag, and width of the closing tag. In some cases, the array will contain two more elements, in order: width of whitespace characters between the opening tag and first child, and width of whitespace characters between the last child and closing tag. All of these positions and widths are measured in UTF-8 bytes.
