Set-PSHCellColor doesn't work for properties in the first column


```
$StartHTML = @"
Column1,Column2,Column3,Column4,Server
1,2,3,4,ServerA
1,1,2,4,ServerB
1,1,1,1,ServerC
test,one,two,three,ServerA
4,4,4,4,ServerB
4,3,2,1,.[?]\
"@ | ConvertFrom-Csv | ConvertTo-Html
$StartHTML | Set-PSHCellColor -Color Red -Filter "Column1 -eq 1" 
```

The output has no style="background-color:Red"
