Why the Gap Appears
Textarea, being an inline (or inline-block) element, reserves space for descenders in text. As a result, a gap may appear beneath the textarea. The variation in gap size between browsers remains unclear.

Explanation
By setting vertical-align to top, the textarea is vertically aligned with the top of its content, effectively removing the reserved space for descenders and resolving the inconsequential gap.
