Fix mousewheel behaviour in textarea (#6641)

Allowing scrolling with the mousewheel when the vertical scrollbar is hidden, unnecessarily exposes oversized containers and newlines at the end of the text. For example try scrolling over the textareas in the pause menu. This PR addresses the issue by requiring the scrollbar to be visible before allowing the scrolling with the mousewheel.
