The scenario I was referring to was when expanding the width of the TextField.  As it tries to reposition the text, the movement is jerky - try setting the cursor to left of the last character and compare it with when you set the cursor at the right of the last character (the end of the text).  The latter is smooth(er).

Then try to compare the same scenario with JTextField (Tools -> JTextArea/JTextField Embedded in SwingNode, you might need to git pull https://github.com/andy-goryachev-oracle/MonkeyTest)

Swing does it much smoother because I suspect it tries not to allow for blank space at the end of the field.

I am suggesting we might try doing something that would make the overall experience a bit smoother, if possible.  But if it is too much work, the fix in this PR can still be considered an improvement.
