fix: pass currentTarget to onFocus

[csantos1113]

Describe the issue/change

This change is based on https://stackoverflow.com/a/66086044 currentTarget: only exists if used right from the onFocus event; but we get currentTarget null because onFocus(e) is called within a timeout.

Hey @csantos1113 , was little occupied with some personal things for last 4 months, so didn't check.
The changes looks good. Please do accompany the fix with a test.
