Current behavior

Since version 5.2.1 we have new clear icon appearing in dropdowns.
It is now appearing in paginator of p-table who has rowsPerPageOptions attribute.
This functionality is unwanted and undefined for the rowsPerPageOptions dropdown.
We must always have a value for Rows Per Page, so the user must not have the ability to clear it.

Expected behavior

This new little clear icon should be suppressed in the p-table p-paginator.

Minimal reproduction of the problem with instructions
See the Demo Plunkr which has a p-table with a p-paginator with a p-dropdown with the unwanted clear icon.
Try clicking the clear icon in the paginator. See it provides no functionality.

What is the motivation / use case for changing the behavior?

User should never be able to clear the Rows Per Page which would cause undefined pagination.
