Which package(s) are affected?

Virtualizer (@lit-labs/virtualizer)

Description

When slotting places a Virtualizer within a scrolling parent, the current parent gathering workflow does not acquire that parent. This means that when the content is scrolled, the virtualization is not triggered and subsequent pages of content are not rendered.
