/**
 * Internal implementation - not to be instantiated directly.
 * This matcher is optimized for the success use-case. In that case it match for a single element
 * with exact number of elements wanted.
 * In case of failure, it will make another call to get the actual number of elements on
 * the page, in order to provide a detailed error message.
 * So the trade off is: In case of success it's faster, In case of failure it's slower. It makes sense since most
 * of the time we expect success.
