Expanding class tree doesn't show individuals

[jamesamcl]

Describe the bug The class tree appears to be expandable to show indiviudals, but when I expand the class node the individuals are not shown

To Reproduce Go to https://www.ebi.ac.uk/ols4/ontologies/iao/classes/http%253A%252F%252Fpurl.obolibrary.org%252Fobo%252FIAO_0000225?lang=en and expand obsolescence reason specification
