Dropdown datagrid paging - show total number of rows


I have an issue concerning dropdown datagrid component with paging. I am using a VS2022 as IDE.
When setting property ShowPagingSummary="true" with the PageNumbersCount property set to value bigger than 1, I got weird behavior in dropdown paging section. Please check the screenshot attached.
Is it possible to set the width of dropdown instead of just column width?

Thanks in advance
