When inside a wizard, Step 1 has a fairly lengthy field editor component. The user doesn’t have to fill out all fields on this field editor, so it’s possible (or even likely) the user won’t scroll to the bottom of the page before moving forward to Step 2.
After moving to Step 2, if the user navigates back to Step 1, the screen positions itself vertically halfway down on the field editor component, which can be a bit confusing to the user and the user has to scroll back up.

I’ve come across this a couple of times, but can’t seem to find anything in the forums.
