Describe the Bug

Steps to Reproduce

1. Create the following Conditional property

    {
      "type": "Text",
      "value": "displayed when static is 100",
      "binding": {
        "name": "text",
        "type": "zeebe:property"
      },
      "condition": {
        "property": "number-static",
        "equals": 100
      }
    }

1. Add to element
2. Even when number-static has value 100, the text is not shown

Expected Behavior

I can set the expected value as a number
