Undoing changes to style sheets

There is a known problem when undoing changes made to TopLeaf stylesheets created by the Map, Notes, and Header & Footer managers and where the stylesheets are shared by more than one partition.

The fault occurs if you make stylesheet alterations using one partition and then open another partition and try to undo the stylesheet changes. The problem occurs because the undo state is held as a property of a partition, and not as a property of the style sheet.

Workaround: Do not make style sheet alterations using one partition and then open another partition and try to undo the style sheet changes.
