Dataset Viewer issue for vadis/sv-ident
Thanks for reporting, @e-tornike 

Some context:
- #4527 

The dataset loads locally in streaming mode:
```python
In [2]: from datasets import load_dataset; ds = load_dataset("vadis/sv-ident", split="validation", streaming=True); item = next(iter(ds)); item
Using custom data configuration default
Out[2]: 
{'sentence': 'Im Falle von Umweltbelastungen kann selten eindeutig entschieden werden, ob Unbedenklichkeitswerte bereits erreicht oder überschritten sind, die die menschliche Gesundheit oder andere Wohlfahrts»güter« beeinträchtigen.',
 'is_variable': 0,
 'variable': [],
 'research_data': [],
 'doc_id': '51971',
 'uuid': 'ee3d7f88-1a3e-4a59-997f-e986b544a604',
 'lang': 'de'}
``` ~~I have forced the refresh of the split in the preview without success.~~

I have forced the refresh of the split in the preview, and now it works. Preview seems to work now. 

https://huggingface.co/datasets/vadis/sv-ident/viewer/default/validation OK, thank you @e-tornike.

Apparently, after forcing the refresh, we just had to wait a little until it is effectively refreshed.  I'm closing this issue as it was solved after forcing the refresh of the split in the preview. Thanks a lot! :)
