Get-AzStorageBlob drops pipeline output when piped to Select-Object -First 1 (prints table but returns $null)

### Description

When piping Get-AzStorageBlob to Select-Object -First 1, no object is emitted to the pipeline (assignment becomes $null) even though a formatted table is printed to the console.

```
(Get-AzStorageBlob -Context $ctx -Container $Container -Prefix $Prefix).Count # 48

$b = Get-AzStorageBlob -Context $ctx -Container $Container -Prefix $Prefix | Select-Object -First 1 # table is printed to host
$null -eq $b # True

# Last works
$c = Get-AzStorageBlob -Context $ctx -Container $Container -Prefix $Prefix | Select-Object -Last 1
$null -eq $c # False
```
