Thanks for the above details Andy.
I saw this behavior with the source code given in the bug as well.

I believe in this case, it gets aligned to the right because text width is less than text field width.

Yes setting a long text is resulting in this behavior. I fixed the bug based on this behavior itself.

Yes this have to be discussed if we want to change the initial behavior of the text alignment.
