Short description of error
Hitting the Home hotkey in the outliner seems to minimize the hierarchy tree instead of fully expanding it. Issue seems present in 2.80 & 2.81 as well.
Exact steps for others to reproduce the error
Create a parented hierarchy of test objects, minimize the outliner tree, then try to expand with Home key or View > Show Hierarchy.
