UI reporting incorrectly that a delta is not in the lookup

[kinow]

Describe the bug

From Element, reported today by @dwsutherland . In the screenshot below, it's possible to see an alert error message for a delta missing from the lookup. But since we have the updated and pruned deltas, both in the same delta, it should be already in the lookup map.

Unless... it never arrived in an added delta? But in this case maybe we are adding nodes in updated too? Will have to confirm.

Release version(s) and/or repository branch(es) affected?

master

Any workflow with a family above root seems to generate this error.

This one does it every time a new cycle point is spawned:

[scheduling]
  cycling mode = integer
  initial cycle point = 1
  runahead limit = P1
  [[graph]]
     P1 = "f1"
[runtime]
  [[FAM]]
  [[f1]]
     inherit = FAM

Detail from the browser console:

Updated node [oliverh|fam/run5|49|FAM] not found in workflow lookup 
{id: 'oliverh|fam/run5|49|FAM', state: 'running', __typename: 'FamilyProxy'}
id: "oliverh|fam/run5|49|FAM"
state: "running"
__typename: "FamilyProxy"
