[ic-side-navigation] Icons only appear after expanding and collapsing again

## Summary of the bug
When creating a nextJS application and adding an `IcSideNavigation`, the icons for navigation items only appear after opening and closing the side nav once. This occurs every time you refresh the page.

## 🪜 How to reproduce
Tell us the steps to reproduce the problem:
1. Create a nextJS app
2. Add an `IcSideNavigation` to a file
3. Bring the exported side nav into the `app.tsx` file inside of a SessionProvider
4. Run your app
5. See the error

## 🧐 Expected behaviour
Icons should load first time and shouldn't require extra clicks to be visible.

## Additional info
I can provide code for this internally if you can't recreate it.
It also happens if side nav is just put directly into the `app.tsx` file, it's not specific to being in a separate file

Reproduce the issue in a nextJS application by adding IcSideNavigation to app.tsx, both directly and inside a SessionProvider. Check the initial render after a page refresh and compare it with the state after opening and closing the navigation. Done means navigation icons are visible on the first load without extra clicks.
