Text repositioned using arrow keys (in edit mode) not added to undo list

While editing text, when the text cursor reaches the left or right of the text field, then the arrow keys start moving the position of the text box. I presume this is the expected and desired behavior.

However, the resulting text move is not added to the undo list. Pressing the undo button after moving text this way has the effect of undoing what was done *PRIOR* to the text box being repositioned. And of course it leaves the text where it was moved to.

I've observed this on Staff Text, and also the Title, but my guess is it happens on all text field types.
