TreeRow

Remarks

⚠ Rebound rather than rebuilt. Scrolling a tree recycles these — the row that leaves the top is the row that appears at the bottom, with a different node in it — so a scroll costs a handful of property writes rather than a tear-down and a rebuild of everything on screen. It is also why the row holds its node rather than the other way round.
