Fixed lazyRoot functionality (#33290). Changed the unique id for Intersection Observers discrimination since previously they were only identified by the different rootMargins, now each being identified by the rootMargin and the root element as well
Added more Images to the test with different margins and with/without lazyRoot prop. Browser correctly initially loading two of the four Images according to the props' specifications.
