Styles are not updated while binding the DataGrid column’s HeaderTemplate and HeaderStyle using DynamicResource

### Description

When assigning a DataGrid column's HeaderTemplate or HeaderStyle with {DynamicResource ...}, the header is not displayed/styled.

```

```

**Note:**
The same templates/styles work correctly when referenced with {StaticResource ...}.
```

```

Please refer the Screenshot for your reference

### Reproduction Steps

1. Run the sample and observe the headers of the two DataGrid columns.
2. The column that uses StaticResource displays the expected header style and template, whereas the column that uses DynamicResource appears unstyled and shows a blank header.

### Expected behavior

The DynamicResource-referenced column header should rendered/styled correctly.

### Actual behavior

The DynamicResource-referenced column header is not rendered/styled correctly.
