This is a follow-up of https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/22504#note_111945170. When using the `v-gl-tooltip` directive from gitlab-ui and the `title` attribute changes, a visible tooltip is not updated. To see the new content, a user needs to hover the element again. It may be necessary (or at least a good idea) to fix this upstream in https://bootstrap-vue.js.org/.
