  issue (non-blocking): I don't love this, but I understand that this is the approach currently implemented in the Test Cases issuable.

  Here's a patch that exclusively uses Vue events and consolidates the sidebar-toggling logic to issuable_sidebar_root.vue: toggle-sidebar-refactor.patch.

  I think the changes in that patch are significant enough for a follow-up MR (which I'm happy to create 😀) - WDYT?
