[NcAppSidebar] Title should be word wrapping

[Victor239]

I was told the issue reported here is due to a component from this library.

Expected: Titles should be word wrapped instead of ellipsis so they're entirely readable, or at least have the default option for it to be this way.

I agree it would be good to let them wrap.at least one additional line...
