Dependent Picklist not populating values from record collection at all

[bribernss]

Is your feature request related to a problem? Please describe.
I am aware that "Dependent Picklists are not supported", however it is not clear how exactly they are not supported. It is ambiguous if the actual dependency rules are not supported vs if they don't work at all, etc, However, in my case, it seems that when I use a record collection to populate the datatable and one of those fields in a column is a dependent picklist, nothing populates at all to the table for that field.

Describe the solution you'd like
At least display the value from the source record collection if one exists instead of it being blank in the table.

Describe alternatives you've considered
In my case, the only alternative is to use the Salesforce standard Datatable component which is not editable, then loop through individual records with a screen one by one.

Additional context
More documentation on what happens with dependent picklists, if used, would be appreciated on the unofficialsf site. Thank you!
