The auto-sizing mechanism in vaadin-text-area incorrectly adds the padding of the native textarea to the calculated size of the content, thus increasing the size of the component (or the scrollable area) by that padding once it starts to grow. This removes the padding from the calculated content size.
Currently only noticable in the Material theme which applies a padding on the native textarea. This should also help with #1399 where calculating a max-height based on a number of rows needs to align with the auto-sizing mechanism.
