Expand sidebar entry by default, if sub-item is active

[kschiffer]

Summary

If a route is active whose link resides as a subentry of our sidebar component. The subentry should be expanded initially by default.

Why do we need this?

To improve contextual awareness for the user.

What is already there? What do you see now?

The entry is collapsed by default, when a subentry is currently active.

What is missing? What do you want to see?

The entry being expanded.

Environment

Console in browser.

How do you propose to implement this?

We need to make the sidebar component aware of the current route and use the info to open subentries if necessary.

Can you do this yourself and submit a Pull Request?

I can but maybe @bafonins is better suited as component author. Feel free to reassign.
