Created attachment 275987 [details]
As seen on Safari 9.0.3
When a textarea is rendered initially below the fold (below 100vh from the top of the page) the placeholder is not restored fully after some text is put in and then removed until element is blurred.
Confirmed to be reproducible in:
Webkit Nightly r199217
I can reproduce it as well on OS X 10.11.4 in Safari 9.1.
I could fix it by forcing the layout trashing when element's content is empty: http://codepen.io/varjs/pen/JXMvoR
Any activity around this?
