I know the feeling well. As someone who basically unlocks and starts the beginning of every Story Quest, its somewhat hilarious when you stumble upon them.

I remember the Unusual Hilichurl event and accidentally stumbling upon Xiao's story quest which contains weird hilichurls. Or the start of the Weinlesefest with Kaeya suddenly having a much more subdued tone when I triggered Jean's quest.

I don't really get what qualifies for "actively blocking" or not. Hu Tao has been standing in Wuwang Hill over the Oceanid fight for years now and it's never been an issue.
