TetxtAreaItem very narrow on Mobile Safari

[mathias]

Consider the code below,and the attached screenshot please.

Browser.setIsHandset(true);

DynamicForm form = new DynamicForm();
form.setBorder("1px solid blue");
//form.setAutoWidth(); <--- this causes the changed behaviour

form.setReadOnlyDisplay(ReadOnlyDisplayAppearance.STATIC);
form.setNumCols(4);
form.setLinearOnMobile(true);



TextAreaItem area = new TextAreaItem();
area.setTitle("Write!!");
area.setColSpan(3);

TextItem dude = new TextItem();
dude.setTitle("Dude");
dude.setColSpan(2);

CheckboxItem box1 = new CheckboxItem("Box1", "Box 1");
CheckboxItem box2 = new CheckboxItem("Box2", "Box 2");

form.setItems(area, dude, box1, box2);
RootPanel.get().add(form);

If i comment or comment out the "setAutoWidth", the form changes width in browsers as expected.

However i just tried in Mobile safari, and if you setAutoWidth on the form, the textareaitem becomes very narrow, see attached screenshot. I suppose this is not expected behaviour.
