 * We have a source offset (the character index) and a context node given. The offset is in

 * tags. We're searching for an instrumentable node tagged with at least one of the given tags,
 * which is nearest to the given offset according to the guest language execution flow. We find
 * the nearest tagged {@link Node node} in following steps:
 * <ul>
 * <li>When the offset is inside the context node, we search for the first tagged parent node
 * and call {@link #findChildTaggedNode(Node, int, Set, boolean)} to find a tagged child. If we
 * find it, we return it, if not, we return the tagged parent.</li>
 * <li>When the offset is behind the context node, we return the last tagged child of the
 * context node.</li>
 * <li>When the offset is before the context node, we return the first tagged child of the
 * context node.</li>
