When you're editing templates and switch styles because you want to edit that same template on another style, the Templates page doesn't scroll to the correct location.
La la la, I'm editing a template:
However, now I want to edit it on the KH-Flare 2015 style, too, so I switch the style and this is where the Templates page scrolls to:
When it should actually scroll to here so that EXTRA.css is at the of the browser below the toolbar, give or take (I can't get it exact, but IIRC, the line above EXTRA.css (or whatever template) didn't show):
Tested on our test site as well with no add-ons just to be sure.
