I recently released a patch update of a registered package (say `PackageA`). The version number increased from 0.3.1 to 0.3.2.

On a different computer, I installed `PackageB` that depends on `PackageA`. `PackageA` was not installed on this computer directly, but installed recursively via installing `PackageB`. In other words, I had something like

```julia-repl
pkg> st PackageA
    No Matches in `~/.julia/environments/v1.6/Project.toml`

pkg> st -m PackageA
    PackageA v0.3.1

```

At this point, I thought if I do `pkg> up`, then `PackageA` would be updated to the patch release (v0.3.2), but it didn’t. When last time a similar phenomenon happened, I found that the patch release had a conflict dependency with other packages, so I expected this time the reason would be similar. The conflicting dependency could be revealed in the error message that showed up by forcing to install the patch release of `PackageA`. However, this time forcing to install the patch release by `pkg> add PackageA@0.3.2` just succeeded without any errors, which means that the patch release didn’t have any conflicting dependency.

Is this something expected? In other words, should we expect that `pkg> up` does not always update the packages recursively installed via other packages to the latest versions, even if the latest versions do not have any conflicting dependencies?
