The behaviour is not overly intuitive, and the icon wasn't helping (hamburger icon usually means "menu"). Now the back button always goes back to the index, no matter where you are, and there's a tooltip that says "Back to discussion list".

/**
|
|
* The `Navigation` component displays a set of navigation buttons. Typically
|
|
* this is just a back button which pops the app's History. If the user is on
|
|
* the root page and there is no history to pop, then in some instances it may
|
|
* show a button that toggles the app's drawer.
|
|
*
|
|
* If the app has a pane, it will also include a 'pin' button which toggles the
|
|
* pinned state of the pane.
|
|
*
|
|
* Accepts the following props:
|
|
*
|
|
* - `className` The name of a class to set on the root element.
|
|
* - `drawer` Whether or not to show a button to toggle the app's drawer if
|
|
* there is no more history to pop.
