Ideally, we don't want this behavior on our default component so this change should be behind a resize prop and it's probably best to implement min/max rows with this change as well.

[im-adithya]

Sure! I'll change this to a prop then!
But how do we set max rows for a textarea component? (or is it max-height that you are referring to indirectly?)
Because the existing rows prop would kinda set the minimum rows (which is subject to resize unless min-height and max-height are set...)
