We added a similar fix in v2.12.1 for the USS tree, but I noticed that the logic for opening data sets also has the "path separation" issue. This could affect the way data sets are displayed in the editor for Windows users - I haven't tested this action extensively, but we might need a v2.12.2 to resolve this issue.

will create new PR if another release goes out
