* Restore focus highlight on explorer toggle button. Remove `unset: all` declaration causing `outline` property to be unset. This allows the default browser focus highlight to be shown. * Fix semantics of expandable sections (explorer, toc). This adds the appropriate aria attributes for the [disclosure pattern](https://www.w3.org/WAI/ARIA/apg/patterns/disclosure/examples/disclosure-image-description/#javascriptandcsssourcecode) and uses `visibility: hidden` to remove the hidden elements from the focus order without disrupting the animations. Further work is needed on the tree view nodes. * Run prettier for SCSS files.
