Godot add optional left padding to VBox control node?

Question

How can I add optional padding to a VBox control node without having the padding expand the minimum space the entire VBox node takes up?

For example, the layout should normally look like this:

| padding | VBox content | 

But when there's not enough space, the padding can shrink

| padd | VBox content |

All the way down to 0

|| VBox content |

I tried using a margin container, but the margin will not shrink.

Instead of

VBox
'-HBox
  '-Optional padding left
  '-VBox
    '-Content
    '-Content
    '-Content

I did

VBox
'-VBox
  '-HBox
    '-Optional padding left
    '-Content
  '-HBox
    '-Optional padding left
    '-Content

The RectMinSize on the padding is set to 0 horizontally, so the padding can shrink all the way down to nothing. I then set the horizontal size flags of each content and padding to SizeFlags.ExpandFill, and I have the SizeFlagsStretchRatio of the padding set to 0.1, and for the content, it's set to 1. This way, the padding will normally take up a small, fixed % of the space but can still shrink down to 0.

However, I still haven't found a way to make fixed-length padding shrinkable. But for now, I'm happy with using ratio-based shrinkable padding.
