Description

What changed?

Previously, formio.js select component would trigger a blur event upon clicking the select. This PR replaces this behavior by adding the blur event listener to the choicesjs input element

Why have you chosen this solution?

The choicesjs input element is focused upon clicking the select element. So adding the blur event listener to the input element fixes this issue
