Editor expand: 

- Adjust calculation when comparing sidebar position to wpfooter top. Fixes an annoying jumping when the user scrolls off the bottom.
- Use a var for the 'bottom' distance of the sidebar.
- Fix sidebar pinning when it's height is nearly the same as the viewport height.
Fixes #29349
