#1962 Close button can close more than one file at once.

This may be an edge case; after some testing I think it only happens if you first open a
file that has been opened before (and had some element selected), then opening a file that
had never been opened before, then press Close. This will close both files. Probably needs
"Save session on exit" setting enabled too.
