There was a problem hiding this comment.
I think we still need the _hasFocus part of this check. Otherwise we'll end up applying the margin on elements the user isn't interacting with.
When we measure the size of the autosize textarea, we make it temporarily smaller which can cause the scroll position to shift. These changes add a workaround that assign a temporary margin-bottom while measuring. Fixes angular#23834
