In the Gutenberg plugin, a position block support feature was introduced last year, that allows a Group block to be set to a "sticky" position, meaning that when the page scrolls, the block will stick to the top of the window.

This change merges the "sticky" position feature for blocks introduced in Gutenberg 15.0.
