6.2.0 doubling story list for title prefix `/`

[hatkyinc2]

Describe the bug Updated to 6.2.0 from 6.1.21

And am getting my story list doubled:

You can see that one is straight on the root level and another is with an empty header

It could be that I'm doing something weird by naming my stories starting with /, like

title: '/Atoms/Plant Image Skeleton',

To Reproduce

Expected behavior This is a screenshot with sb 6.1.21:

Code snippets As mentioned before this is my title that could be "weird"/edge case/..

title: '/Atoms/Plant Image Skeleton',

Indeed this is a corner case. As a workaround, I'd recommend removing the leading slash. Nevertheless it also looks like a bug since it's duplicating the UI.
