Crash on reloading a page with slide anchor

[BenjaminSYD]

Description

When using data-anchor with slides, if I reload a page with a slide anchor in the url the app crashes with error message "can't access property "item", r.activeSlide is null".

Link to isolated reproduction with no external CSS / JS

Steps to reproduce it

1. Open codesandbox link.
2. Go to "Slide2" using right arrow button.
3. Notice that "#section1/Slide2" is added to the url.
4. Reload the page inside codesandbox (not codesandbox itself).
5. Observe the application crash.

I'm not able to reproduce this issue outside codesandbox.
Have you tried it outside?

I can reproduce it in a larger-scale project (I can't share it), but not in a minimalist one.

My assumption is that it could be a concurrency issue occurring in slower environments (heavy app or codesandbox). I will try to reproduce it again another time.
