Subject: Fix IntersectionObserverArticle not hiding some out-of-view items (#9982)
X-Git-Url: https://git.xn--scling-oua.cat.family/?a=commitdiff_plain;h=d09ce6d81b542705fcce8f5091d032471531c755;p=mastodon.git

Fix IntersectionObserverArticle not hiding some out-of-view items (#9982)

IntersectionObserverArticle is made to save on RAM by avoiding fully rendering
items that are far out of view. However, it did not work for items spawned
outside the intersection observer.
