Run the attached test. You will see a text box, button, password box and a text node all added to a vbox. Text node's content is bound to rawText of the textbox. Now when I start typing the text in the textbox, the textbox size keeps growing as the size of the text node increases. Other controls remain unaffected. This behavior is introduced in Soma-b29 and not reproducible on Soma-b28.

I reproduced it on Soma-b30, WinXP.

I suppose this is due to grow/shrink changes and I am not sure if this is intentional but will be the ugliest of behaviors even if this is intended.
