Hello! I'm working on my platformer and now I have some trouble with the dialogbox when window expand.

Here my Strech setting, I want to keep the height so that I can show UI on right and left hand side. So I set the aspect to "keep_height". Set the Dialog Box to align as top center anchor(0,0,1,0) and set it margin top 32px.

Everything look good to me (like image bellow)

Until I scale the window in horizontal :> It's break the rule

What should I do? I just want the dialogue box be align at the center no matter how big the width of screen is. Thanks!
Btw, Is it any way to set Anchor Mode of the default camera (Scene without Camera2D node)
