bAt the moment when editing the text size, the size of the text field changes but is anchored to the top left, even when the text is right justified. This means that increasing or decreasing font size can mean also having to re-arrange the text box to get it back into the correct position.

When text is aligned to the right, the automatic scaling of the text box should be top-right aligned. When text is centre aligned, the scaling should be top-centre aligned.
