Previously, the `{{mobile-nav}}` component required a `currentRouteName` property, passed from the router service. It would observe changes in this property, and update the UI accordingly.
If we change between routes which have the same `currentRouteName` (e.g. two different group message inboxes), then the `currentRouteName` does not change and does not trigger the observer. Currently in core, we are relying on the fact that currentRouteName temporarily enters a `.loading` substate during a transition. This will change when we remove the loading substate in the near future.
This commit refactors `{{mobile-nav}}` to inject the router directly, and use the `routeDidChange` event instead of an observer. The change is backwards compatible, but plugins passing the old `currentPath` property will be shown a deprecation notice.
Includes:
* FIX: Don't override computed properties
* FIX: Prevent a set-after-destroy error
* FIX: Get rid of select-kit deprecations
* FIX: Replace removed admin-group-selector
* FIX: Provide onChange action to fix warnings
* FIX: Remove an element with an invalid id
* DEV: Remove topic-notifications-button from dropdowns
It has its own styleguide section under "Molecules".
* UX: Styleguide tweaks
* DEV: Make the dropdowns useable
This plugin is only useful for developers, however, making it core allows us to centralize any component modification in one commit.
This integration also adds a new site_setting: `styleguide_admin_only` which allows to enable a styleguide on a live site while restricting visibility to admins only.
By default, styleguide is disabled.
