Global GlPopover mock misses named slot
In the global @gitlab/ui
mock, GlPopover
renders only a default slot: https://gitlab.com/gitlab-org/gitlab/-/blob/master/spec/frontend/mocks/@gitlab/ui.js#L25
However, real GlPopover
also contains a title
named slot: https://gitlab.com/gitlab-org/gitlab-ui/-/blob/master/src/components/base/popover/popover.vue#L27
This results in failing unit tests when we try to stub GlPopover
(you can find related discussion here)
It would be nice to add a named slot to global mock.
