> Each entry in {{MemoryDiffCache}} is keyed with {{(path, fromRev, toRev)}} for the list
of modified children at {{path}}. A diff calcualted by {{DocumentNodeStore.diffImpl}} at '/'
(passively via loader) or {{JournalEntry.applyTo}} (actively) fill each path for which there
are modified children (including the hierarchy)
> But, if an observer calls {{compareWithBaseState}} on a unmodified sub-tree, the observer
will still go down to {{diffImpl}} although cached parent entry can be used to answer the
query.
