[WEB-493] chore: custom search select input key down improvement

[anmolsinghbhatia]

Problem:

1. Within the peek overview, when opening any search select dropdown and typing into the search input, pressing the escape key closes the peek overview instead of clearing the typed input.

Solution:

1. Address this by implementing an input keydown handler that clears the typed input in the dropdown search, ensuring expected behavior.
