Bug 1892429 - Create an expanded sidebar state r=sidebar-reviewers,fluent-reviewers,kcochrane,sclements,extension-reviewers,robwu
Adds an `expanded` property, which, if enabled, shows labels along with their respective icons within the sidebar menu. Currently, this property is not controllable from the UI. As I understand it, the follow-up bugs are responsible for addressing that.
