Unity Editor Textfield appearing in the center

I’m making a custom editor window and when generating a new textfield and then expanding the height, the text appears in the center of the textbox instead of the top left corner. How do I make the text start at the top left corner of the textbox after resizing?

I’m basically just doing

var textbox = new TextField
style = { height = 200} };

and then adding it to the root visual element.
image of what i mean below. Text in the middle of the box is not intended

It would probably be better to use TextArea rather than TextField in this case;

TextField only lets you write a single line, so it makes sense that the text would auto-centre vertically.
