Units for a list of values not displayed in the tree view

[jkotan]

Summary

Units for a list of values are not displayed in the tree view. It looks weird in the scientificMetadata where 0D and 1D values are present.

Steps to Reproduce

Ingest scientificMetadata with list value e.g.

{
  "stth":
    {
      "value" : [0.1, 0.2, 0.3, 0.4],
      "unit": "deg"
    }
}

e.g.

Current Behaviour

Units for 1D values are not displayed

Expected Behaviour

Units for 1D values should be displayed in a bracket as for 0D values
