ViewConfig carries group_by_depth -- alongside the split_by_depth this fork
added -- so row depth can be set declaratively:
await viewer.restore({ group_by_depth: d })
The config is what the viewer rebuilds its view from, so the depth survives
every rebuild by construction, and viewer.save() carries it into the
persisted and named layouts for free.
It had been imperative: getView() then view.set_depth(), which puts the
depth on an object the viewer discards whenever it re-renders. Everything
that grew around that existed only to guess when a rebuild had happened and
put the depth back -- a shim patching window.IntersectionObserver and
window.ResizeObserver, focus/visibilitychange/pageshow listeners, a retry
loop for getView() throwing "No table set" while getTable() resolved, a flag
tracking whether the viewer had "gone away", and tracing to debug all of it.
That guesswork caused three separate visible faults in a single session: the
tree fully expanding on refocus, snapping on any reflow, and snapping when
Perspective's own settings sidebar was opened. Each fix was a finer
heuristic about which browser event meant what, which is the shape of
fighting a framework rather than using it.
312 lines out, 35 in. applySplitDepth no longer re-applies the row depth
after truncating split_by, because the rebuilt view brings it along.
expand_depth stays readable on load: it is the legacy key, from when the
depth had to be stored beside the config rather than in it.
