Describe the bug
Datagrid rows can be filtered by setting a filter on one of their columns. When applying a filter on multiple columns the UI indicates that multiple columns are being filtered by. However not all of the filters are actually applied to the rows.

To Reproduce
Steps to reproduce the behavior:

  1. Go to https://blazor.radzen.com/datagrid-performance
  2. Click on the Filter Symbol on the column "First Name"
  3. A popup opens that lets you apply filters to this column
  4. Click on the first input Field
  5. Type "Nancy"
  6. Click Apply
  7. The Datagrid displays a loading symbol for a short time
  8. Once the loading symbol disappears, 5 entries of an employee with the First Name Nancy and Last Name Davolio appear
  9. Click on the Filter Symbol on the column "Last Name"
  10. Click on the first input field
  11. Type "asd"
  12. Click Apply

Expected behavior
The employee with First Name Nancy and Last Name Davolio no longer appears in the Data Grid, as her last name does not contain "asd".

Observed behavior
The employee with First Name Nancy and Last Name Davolio still appears in the results of the DataGrid. Both the filter icon on the First Name and on the Last Name column indicate that a filter has been set. Upon clicking on the icons, we can still see the filters that we have set.

Hey @uflowie,

The filter operator between column filters in this demo is set to OR:
