Issues with input_number

[VirtualL]

Hi, I getting this Warning : https://MYSERVER.COM/frontend_latest/eb618cf11a4eca6918ea.chunk.js:266:14994 TypeError: null is not an object (evaluating 'this.shadowRoot.querySelector("paper-slider").offsetWidth')

The config:

      - type: custom:vertical-stack-in-card
        cards:   
          - type: markdown
            content: >
              ### Alarm Clock

          - type: entities
            entities:
              - input_boolean.alarm_clock_status
              - entity: sensor.alarm_clock_time
                name: Selcted Time
              - input_number.alarm_clock_minute
              - input_number.alarm_clock_hour

If I will remove the input_number entities , the warning will disappear

Thanks again!

      - type: entities

It looks like it's issue in HA. Polymer issue #1578 Lovelace UI issue #118

I really don't know why the error does not appear on vertical-stack card.
