Steps to replicate the issue (include links if applicable):
- Use Vector-2022
- Pin everything! Main menu, TOC, tools and appearance menus.
- Go to a section of a page that is pretty far down the page, like https://en.wikipedia.org/wiki/Nauru#Effects_of_mining
- Hard refresh the page
What happens?:
Before the sticky header appears, the pinnable menus are placed at the very top of the page. But once it appears (with a CSS transition), the pinnable menus "jump" down to give space to the header.
What should have happened instead?:
Since the sticky header appears with a smooth transition, the transition for the pinnable menus should similarly be smooth.
