[data grid] aggregationModel does not show noRowsLabel if no rows are provided

[yoshegg]

Steps to reproduce

1. Open this link to live example: https://codesandbox.io/p/sandbox/aggregationmodel-norowslabel-96sfdg?from-embed=&workspaceId=ws_12jL538MCCJzkRwuZb5qo3
   • Two DataGrids are being shown. First one has aggregation, second does not. Only the second shows the noRowsLabel "No rows"
2. Press "Add row" button
   • Both tables now show a row, the first one also shows a summary row.
3. Press "Remove row" button
   • Both tables are empty again, but only the second shows "No rows"

Current behavior

cf. "Steps to reproduce"

Expected behavior

The DataGrid with aggregationModel should also show "No rows".

Context

The error can be bypassed by checking if rows exist and only then set the aggregationModel to a filled object. Otherwise it must be an empty object (but not undefined!)

Check line 28 in the example: an alternative to the aggregationModel prop.

Hey! I posted in the wrong repo by accident so I didn't see your report.

I also noticed the same issue this morning and have made a ticket here: #16458

[KenanYusuf]

Thanks for raising the issue @yoshegg and @db-qc.

Looks like this is a regression introduced in v7.23.2 by this PR #15335
