no issue
- a change in Ember 3.10's rendering has resulting in the component's element being removed before the `{{gh-markdown-editor}}`'s cleanup action is run which meant that we were trying to run `.querySelector` on `undefined`
- removes the code which moved toolbar elements around because it hasn't been used since we moved to Koenig, this meant that the cleanup action could also be removed
