The problem

The was an issue introudced in M1 that stopped variables definitions from being applied as per the following issue:
#3939

This was fixed, however I now see that the defintion does not seem to be aplied in the Widget Editor, though does still work when implemented for example on teh Overview Page etc.

Expected behavior

The variable definition to work in the Widget Editor in teh same way as it does when implemented on a page etc.

Steps to reproduce

The following test widget demonstrates the issue:

version: 1
widgets:
  Tes_VariableAction_SNAPSHOT:
    tags: []
    props:
      parameters:
        - description: A text prop
          label: Prop 1
          name: prop1
          required: false
          type: TEXT
        - context: item
          description: An item to control
          label: Item
          name: item
          required: false
          type: TEXT
      parameterGroups: []
    component: f7-card
    config:
      defineVars:
        testVariable: true
      footer: =props.prop1
      title: Test of Variable Action
    slots:
      default:
        - component: f7-block
          config:
            style:
              left: 0px
              margin: 0
              padding: 0
              position: absolute
              top: 45px
              width: 100%
          slots:
            default:
              - component: oh-button
                config:
                  action: variable
                  actionVariable: testVariable
                  actionVariableValue: '=(vars.testVariable == "null") ? true : !(vars.testVariable)'
                  style:
                    height: 100%
                    width: 100%
                  text: OPEN
        - component: Label
          config:
            style:
              color: black
              font-size: 10px
              left: 20px
              position: absolute
              top: 78px
            text: ="Value testVariable - " + [vars.testVariable]

On initial display the widget editior should show the defined "value" of the variable:

As can be seen the variable is undefined even though the definition sets the "value" to true.
