SUMMARY When Dolphin's left sidebar is narrower than the strings in some of the items, there needs to be a tooltip that shows users the full name of the elided string. This way, the user who is scanning without clicking can get a sense of what they are missing without much UI intervention. This is generally a common practice across systems. I think we should integrate that here.
There's an open merge request that would fix this: https://invent.kde.org/frameworks/kio/-/merge_requests/698
