The previous layout lacked a specified gap between the node header and
the documentation toggle button in the tree view. This resulted in a
crowded appearance, making the interface look cluttered and reducing
readability, especially on smaller screens.
This commit introduces a relative gap, adjusting the spacing based on
the text size. This change enhances the visual separation and improves
user interaction by ensuring the documentation button and text do not
overlap, regardless of screen size.
