/* Explanation:
*
* https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollHeight
* scrollHeight returns element's scrollable content height, i.e. visible
* element + overscrolled parts of it. We use it to determine when text
* inside the textarea exceeded its height, so we can set height to prevent
* overscroll, i.e. make textarea grow with the text. HOWEVER, since we
* explicitly set new height, scrollHeight won't go below that, so we can't
* SHRINK the textarea when there's extra space. To workaround that we set
* height to 'auto' which makes textarea tiny again, so that scrollHeight
* will match text height again. HOWEVER, shrinking textarea can screw with
* the scroll since there might be not enough padding around form-bottom to even
* warrant a scroll, so it will jump to 0 and refuse to move anywhere,
* so we check current scroll position before shrinking and then restore it
* with needed delta.
