I think, that description can't contain annotation link. Other examples of the fact that there is no description for these kind of pages:
1) https://elementy.ru/nauchno-populyarnaya_biblioteka/432676/Chetyre_stikhii_Empedokla
In this article tells about 6 different practicies, but description taken from first.
2) https://elementy.ru/nauchno-populyarnaya_biblioteka/434543/Mir_v_ravnovesii_drevneyshie_shumerskie_zaklinaniya

Too big first paragraph for description. Description should be short.
3) https://elementy.ru/nauchno-populyarnaya_biblioteka/430622/Dzheyms_Uotson_Chestnost_polezna_etomu_miru_ona_zastavlyaet_mir_rabotat_effektivnee

Iterview again, description contains direct speech. There are may be other pages 1) , 2) or 3) types .
