So I have been playing around with the new Container Layouts and have noticed that they break the responsiveness of the Form's control. As you can see in the screen shot below, the green section is a Horizontal Layout Container and it contains a form. See that it is not filling the rest of the space to the right side, I have Width Fit enabled on those top controls. Also when it does start to fill the remaining space on occassion it extends past the scroll bar (second screen shot)
Now if I take the form out of the container, the responsiveness of the from is back to normal. Everything works like it should.
The question is am I doing something wrong with the form where it does not work in the Container or is there a bug or should we not be putting controls like this in containers?
