When a user selects From RefList Item in the Color Source property, the Chevron component crashes

Steps to reproduce the behavior:

1. Go to 'https://functional-adminportal-test.azurewebsites.net/shesha/forms-designer?id=ea1c8ee3-0103-43b9-8b23-8e2266a9c778'
2. Click on 'Chevron' component
3. From the property panel, click on Color Source
4. From the dropdown options, select 'From Reflist Item'
5. Actual Results: The component crashes immediately after selecting that option

Expected behavior The component should remain functional and display the selected option without crashing

Hi @OmolemoBlessingLethuloe as discussed,

• Let's add a tooltip to alert users that only hex code is supported when using from reflist item option
• Increase the scroller based on the height configured
