The sidebar covers the QuickBar

[fregante]

Being a modal, the QuickBar should be displayed above the sidebar, not below it:

Repro

1. Open sidebar
2. Open QuickBar

Solutions

Quick: I think we just need to bump down the sidebar’s z-index

Alternative: we need to ensure that the order of our UI in the DOM is exclusively:

1. Sidebar
2. Quickbar
3. Notifications

Even if they have the same z-index, they're painted in the order that they appear in the DOM.
