RadzenDropDown.ClearSearchAfterSelection is confusing

[Mertsch]

Describe the bug
When using ClearSearchAfterSelection=True on RadzenDropDown
See https://blazor.radzen.com/dropdown-filtering with ClearSearchAfterSelection=true/>
The filter (not search) is cleared at any time a selection happens. Which is something that happens during the selection itself. Since you are in typing mode while using the filter, it's natural to use the arrow keys to select an item. This clears the filter.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://blazor.radzen.com/dropdown-filtering
2. Add ClearSearchAfterSelection=true
3. Try to use up/down keys on the filtered list
4. See filter disappearing

Expected behavior
My suggestion remove the ClearSearchAfterSelection property (as it's name is misleading) and introduce a ClearFilterOnClose (or similar) and clear the filter value when the user closes the dropdown, which means the user has actually selected something, rather then navigating a list.
