A common issue with most package managers is that if you have A installed, and then you install B which depends on C, and that C happens to also be an optional dependency of A, then uninstalling B will not uninstall C as C won't be orphaned (because of A).
That's interesting. I'm surprised. Just some cursory websearching and didn't see anything that gave a solution here for DNF at least. Funky! Seems like there should be a way to deal with this.
