Resolving this issue would make the formatting (especially the way it is
presented in the Organizer tab) much clearer:

When a style linked with another is modified, the change appears in the
Organizer tab (as it should). But when the formatting is reverted back to the
original formatting of the linked (parent) style, the formatting is not reset to
the original parent formatting but is explicitly set to the reverted value. For
example: 1st we change the Text Body font size to 13pt, then we change it back
to 12pt which is the size of the font for the parent Default paragraph style.
Text body font size is then explicity 12pt, as opposed to being linked with
Default again.

As far as I remember, in older versions of OOo 2, doing the above would cancel
the modification to the child linked style and revert it back to the linked
style (parent) formatting. Maybe there should be a mechanism for reverting back
to linked style?
