Some existing pages that include text in classic editor, have the text migrated as "Classic editor" native block. However the text is not always migrated properly. The following issues have been found:

1. No vertical spacing
Example:
Gutenberg: https://k8s.p4.greenpeace.org/argentina/campanas/climayenergia/
Classic: https://greenpeace.org/argentina/campanas/climayenergia/

2. Text is missing
Example:
Gutenberg: https://k8s.p4.greenpeace.org/argentina/campanas/oceanos/
Classic: https://greenpeace.org/argentina/campanas/oceanos/

Example:
Gutenberg: https://k8s.p4.greenpeace.org/nl/oplossingen/natuur/
Classic: https://greenpeace.org/nl/oplossingen/natuur/
