The bleedY prop removes the excess vertical space created by the toggle input — ensuring it’s only as tall as the provided label text.
This better aligns with the layout principles of the system, enabling the surrounding white space to be controlled by the parent layout component, e.g. Stack.
In the future this will become the standard behaviour. Migrating layouts to work with this option now is recommended.
In the following example, a Stack controls the space between child elements. Switching the toggle off introduces unwanted space above and below the label.
