A session whose loaded rows were shorter than the viewport drew them
against the top of the list, leaving a gap between the newest message and
the box you type in -- and nothing to scroll, because there was no
overflow. Opening the keyboard shrank the viewport enough for the content
to overflow it and the list snapped down, which made a placement fault
look like a scrolling one.
`reverseLayout` defaults the arrangement to `Bottom` on its own, but
naming `spacedBy` replaces that default with `spacedBy`'s own, which is
`Top`. The arrangement is only consulted when the content does not fill
the viewport, which is why this sat here since 2026-08-28 without being
seen: it needs a session that loads less than a screenful, and a page of
tool calls collapsing to one "Called 80 tools" row is how a long
conversation manages that.
