UDTable seems to always sort unique - why?

very simple page, displaying a table.
The data is an array.
Now if there are 2 items in the array that are identical, the table will show only one.
Why?
It seems it does a sort -unique over all properties.
An array or a table is supposed to contain multiple rows of the same data…


$page:foo=@{
    data=0..0xf|%{@{ name="none"; value="none"}} 
}

New-UDButton -id "button" -text "click" -onclick {
    $page:foo.data=@()
    $page:foo.data+=@{name="1";value="one"}
    $page:foo.data+=@{name="2";value="two"}
    $page:foo.data+=@{name="3";value="three"}
    $page:foo.data+=@{name="3";value="three"}
    $page:foo.data+=@{name="4";value="four"}
    Sync-UDElement -id "table" -wait
} -ShowLoading

$columns=@(
    New-UDTableColumn -Property name
    New-UDTableColumn -Property value 
)
New-UDTable -id "table" -Dense -columns $columns  -loaddata  {
    $tdc=$page:foo.data.count
    $page:foo.data | Out-UDTableData -Page $EventData.Page -TotalCount $tdc -Properties $EventData.Properties
}

So if I add another hidden column like idx and put some unique values in, the table gets displayed as expected


$page:foo=@{
    data=0..0xf|%{@{idx=$_; name="none"; value="none"}} 
}

New-UDButton -id "button" -text "click" -onclick {
    $page:foo.data=@()
    $page:foo.data+=@{idx=$page:foo.data.count; name="1";value="one"}
    $page:foo.data+=@{idx=$page:foo.data.count; name="2";value="two"}
    $page:foo.data+=@{idx=$page:foo.data.count; name="3";value="three"}
    $page:foo.data+=@{idx=$page:foo.data.count; name="3";value="three"}
    $page:foo.data+=@{idx=$page:foo.data.count; name="4";value="four"}
    Sync-UDElement -id "table" -wait
} -ShowLoading

$columns=@(
    New-UDTableColumn -Property idx -hidden
    New-UDTableColumn -Property name
    New-UDTableColumn -Property value 
)
New-UDTable -id "table" -Dense -columns $columns  -loaddata  {
    $tdc=$page:foo.data.count
    $page:foo.data | Out-UDTableData -Page $EventData.Page -TotalCount $tdc -Properties $EventData.Properties
}

I think this is wrong behavior.
A table should by default be able to display any list of data.
Even if all rows are the same.
