/**
 * Generate arrays that indicate which node belongs to which subset,
 * or whether it's actually an orphan node, existing in only one
 * of the two trees, rather than somewhere in both.
 *
 * So if t1 = <img><canvas><br>, t2 = <canvas><br><img>.
 * The longest subset is "<canvas><br>" (length 2), so it will group 0.
 * The second longest is "<img>" (length 1), so it will be group 1.
 * gaps1 will therefore be [1,0,0] and gaps2 [0,0,1].
 *
 * If an element is not part of any group, it will stay being 'true', which
 * is the initial value. For example:
 * t1 = <img><p></p><br><canvas>, t2 = <b></b><br><canvas><img>
 *
 * The "<p></p>" and "<b></b>" do only show up in one of the two and will
 * therefore be marked by "true". The remaining parts are parts of the
 * groups 0 and 1:
 * gaps1 = [1, true, 0, 0], gaps2 = [true, 0, 0, 1]
