Only first Option is displayed if form depends on custom attribute

Consider the following code:

const container = document.getElementById('div-optionsFieldDependingOn')
      const already = {}
      const subject = UI.rdf.namedNode('http://example.com/#this')
      const exampleOptionsField = UI.rdf.namedNode('http://example.com/#exampleOptionsField')
      const store = UI.rdf.namedNode('http://example.com/#store')
      const callbackFunction = (ok, errorMessage) => {
        console.log(ok, errorMessage, document.getElementById('div-optionsFieldDependingOn').innerHTML);
      }

      // This form depends on colour:
      UI.store.add(exampleOptionsField, UI.ns.ui('dependingOn'), UI.rdf.namedNode('http://example.com/#persona'), UI.rdf.namedNode('http://example.com/'))
      
      // UI to display in case subject is blue:
      UI.store.add(exampleOptionsField, UI.ns.ui('case'), UI.rdf.namedNode('http://example.com/#if-subject-is-developer'), UI.rdf.namedNode('http://example.com/'))
      UI.store.add(UI.rdf.namedNode('http://example.com/#if-subject-is-developer'), UI.ns.ui('for'), UI.rdf.namedNode('http://example.com/#developer'), UI.rdf.namedNode('http://example.com/'))
      UI.store.add(UI.rdf.namedNode('http://example.com/#if-subject-is-developer'), UI.ns.ui('use'), UI.rdf.namedNode('http://example.com/#ui-for-developers'), UI.rdf.namedNode('http://example.com/'))
      UI.store.add(UI.rdf.namedNode('http://example.com/#ui-for-developers'), UI.ns.rdf('type'), UI.ns.ui('Comment'))
      UI.store.add(UI.rdf.namedNode('http://example.com/#ui-for-developers'), UI.ns.ui('contents'), '[UI for developers]')
      
      // UI to display in case subject is red:
      UI.store.add(exampleOptionsField, UI.ns.ui('case'), UI.rdf.namedNode('http://example.com/#if-subject-is-power-user'), UI.rdf.namedNode('http://example.com/'))
      UI.store.add(UI.rdf.namedNode('http://example.com/#if-subject-is-power-user'), UI.ns.ui('for'), UI.rdf.namedNode('http://example.com/#power-user'), UI.rdf.namedNode('http://example.com/'))
      UI.store.add(UI.rdf.namedNode('http://example.com/#if-subject-is-power-user'), UI.ns.ui('use'), UI.rdf.namedNode('http://example.com/#ui-for-power-users'), UI.rdf.namedNode('http://example.com/'))
      UI.store.add(UI.rdf.namedNode('http://example.com/#ui-for-power-users'), UI.ns.rdf('type'), UI.ns.ui('Comment'))
      UI.store.add(UI.rdf.namedNode('http://example.com/#ui-for-power-users'), UI.ns.ui('contents'), '[UI for power users]')

      // Subject is both a developer and a power user, so it should display both [UI for developers] and [UI for power users]
      // but see 
      UI.store.add(subject, UI.rdf.namedNode('http://example.com/#persona'), UI.rdf.namedNode('http://example.com/#developer'), UI.rdf.namedNode('http://example.com/'))
      UI.store.add(subject, UI.rdf.namedNode('http://example.com/#persona'), UI.rdf.namedNode('http://example.com/#power-user'), UI.rdf.namedNode('http://example.com/'))
      
      // FIXME: https://github.com/solid/solid-ui/issues/239
      document.outlineManager = {
        appendPropertyTRs: () => {}
      }
      const result = UI.widgets.field[UI.ns.ui('Options').uri](
        document,
        container,
        already,
        subject,
        exampleOptionsField,
        store,
        callbackFunction
      )

You would expect it to display both the developer and the power user UI but it only displays one of them, at random.

Start at the Options widget entry point, UI.widgets.field[UI.ns.ui('Options').uri], and run the reproduction in the issue with a subject having both developer and power-user values. Trace how the dependingOn cases are selected; done means both [UI for developers] and [UI for power users] are displayed consistently.
