/* 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 root 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.
