Current behavior

When a named slot template is used in the Grid, the PDF export functionality will not export the cells that have an applied template.

In the linked below example, after exporting the Grid to PDF, the header cell of the "UnitPrice" column is empty.
If you remove the headerCell: 'headerTemplate' configuration and export the Grid to PDF, everything is exported correctly.

Expected behavior

All Grid cells should be exported to PDF no matter if they have a template applied to their definition.

Minimal reproduction of the problem with instructions

1. Open this project.
2. Click on the "Export vie PDF component" button
3. Check the exported file
