-Name parameter on cmdlets does not do exact match

Given reports/datasets 'X' and 'XY' in workspace :

Get-PowerBIReport -WorkspaceId <id>-Name 'X'
Get-PowerBIDataset -WorkspaceId $<id>-Name 'X'

both return both 'X' and 'XY', which seems to be a bug as if the -Name parameter is doing a substring match? It seems related that sending the TMSL to refresh the dataset 'XY' as below refreshes instead dataset 'X':

{  
  "refresh": {  
    "type": "full",  
    "objects": [  
      {  
        "database": "XY"  
      }  
    ]  
  }  
} 

Start by locating the implementations of Get-PowerBIReport and Get-PowerBIDataset, then inspect the code handling the TMSL dataset name during refresh. Reproduce the examples with reports or datasets named X and XY. Done means -Name and the refresh object select only the exact matching name.
