Циклическая видимость исходного блока в организационном режиме

Это небольшая модификация кода, содержащегося в ссылке, упомянутой в моем первом комментарии выше: https://stackoverflow.com/a/21594242/2112489

Все, что я сделал, это заменил регулярное выражение begin/end html на регулярное выражение SRC. Идите вперед и дать ему вихрь и посмотреть, если это то, что вы ищете. Я оставил там свою предыдущую модификацию сноски.
