As part of this issue we should implement the [hover load directive](https://gitlab-org.gitlab.io/gitlab-ui/?path=/docs/directives-hover-load-directive--docs) in the FTB, ensuring the directory/blob is pre-loaded before users click on it. #### Notes We already use this directive on the [repository file tree row](https://gitlab.com/gitlab-org/gitlab/-/blob/1c818e3dc5f7dfe3fd0e8e1b845c4f458e5fa1d7/app/assets/javascripts/repository/components/table/row.vue#L216), we can use the same implementation for the repository FTB.
