Problem with textarea resizing when scrolling

When scrolling a view with a textarea, the text area changes height while scrolling. After scrolling the original height is restored.

Anyone know how to fix this?

It seems like the input is getting cloned for some reason, the clone doesn’t have “rows” set:

The clone is only present while scrolling while the original one is moved out of the view (left: -9999px).
