Why doesn't the previous() function loop when the find term is the first word in a textarea?

The functionality fails when the search term is at the very beginning of the textarea, as previous navigation does not loop back to the last occurrence.

The next function successfully finds the next occurrence or loops back to the first occurrence when reaching the end of the text, improving usability.

The previous function’s logic only looks backward from the current index, resulting in a lack of wrapping behavior when the match is at the start.
