The circular collapse Icon is used on multiple occasions in our Codebase. The styles are defined in `app/assets/stylesheets/framework/diffs.scss` and have the `diff-notes-collapse` and `diff-codequality-collapse` assigned to it. We need to come up with GitLab UI Vue component or a helper class to make these styles reusable. | screenshot | | ------ | || How to reproduce screenshot: 1. make sure your GDK has an ultimate license 1.
