…endering in the correct position (#189201)

## Summary
Table Pagination popover is not rendering in the correct position under
Uncommon Processes table. This is a custom pagination used under explore
pages.
When user clicked on "Rows per page: 10" pagination button, the popover
with options was appearing in the middle of the table (horizontally).
With this fix it appears where it should.
