The pattern uses clones (<use> objects) - the referenced object is outside the pattern definition, but inside the defs, thus does not get exported to the clipboard (not selected).
AFAIU the underlying issue is already tracked in - Bug #167907 "Copying cloned objects between files fails” <https://bugs.launchpad.net/inkscape/+bug/167907>
Variation with <symbol> elements: - Bug #220521 “Group element in <defs> section lost during copy/paste between inkscape windows” <https://bugs.launchpad.net/inkscape/+bug/220521>
