dataList component does not display data when on designer mode

[hlayisanimazuze]

When you preview to see how the dataList renders on the designer mode, it does not pull/display the data. You have to navigate where the dataList is rendered to see the data

Steps to reproduce the behavior:

1. Go to 'https://function-adminportal-test.shesha.dev/shesha/forms-designer?id=1cacc1e3-2c31-4302-a3bb-5bfedeb02323'
2. Click on 'preview' icon
3. Actual Results: The table pager shows that there is data, however the dataList itself does not display the data
4. Navigate to: https://function-adminportal-test.shesha.dev/dynamic/Boxfusion.SheshaFunctionalTests.Common/list-of-employees-V3
5. Actual Results: The dataList only show data when the form is rendered and not preview in the designer mode

Expected behavior
It should be possible to preview the dataList on the designer mode to see the data
