Subject: Fix crash after 24926b2e239.
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=0e69ecdaf032820b146736c479c2cea465a37dbf;p=features.git

Fix crash after 24926b2e239.

The matched element may not have a parent. I guess the old version of
setExpanded too care of that. Now we have to do so.
