Overflowing style alone is not enough: on layouts where an outer
container scrolls (the web app's conversation scroller), the Context
tab's own .lc-root reports overflow-y auto yet grows with its content
and never moves — taking it short-circuited the walk into a silent
no-op, so neither the team card's jump to the Agent network card nor
the chat→context jump's composition reveal ever scrolled. The walk now
requires scrollHeight > clientHeight, so the first ancestor that can
actually move takes the rect delta (verified live: click lands the
foot card at the scrollport top).
