A blank value appears in the dropdown when PageSize is not within the predefined PageSizes or equals the TotalCount

I've made a simple blazor repl demo here: https://blazorrepl.telerik.com/mmlYatun39gTFEgO21

As you can see, TotalCount is 10, and the current PageSize is also 10. When these values match, the value in the "items per page" dropdown isn't present. Select any other value, and it will be present (for 5, 20, 40). Come back to 10, and again, the value disappears.

After installing version 6.0 there are still issues.

============================

Issues:

1.

Selecting 100 when you have selected f.i.12 before will clear the list.

2. 

Sometimes selecting any value outside the visible items is selected only after another click on the same value
