tdf#155939 sw: fix infinite loop when changing document language
If there's a footnote in the document, changing the document langauge goes into an infinite loop in FindParentText(), because the selection created by ExtendedSelectAll(true) is actually invalid, apparently the intention is that only very limited functions may be called while it is active. Don't handle this invalid "very" extended selection like one created by ExtendedSelectAll(false). (regression from commit d81379db730a163c5ff75d4f3a3cddbd7b5eddda) Change-Id: Icf1032715cf2e0a05bf485039c483440c08bb6bb Reviewed-on: https://gerrit.libreoffice.org/c/core/+/152797 Tested-by: Jenkins Reviewed-by: Michael Stahl <michael.stahl@allotropia.de> (cherry picked from commit ca9341cf60f3f9350662d30b61f6eadefca24667) Reviewed-on: https://gerrit.libreoffice.org/c/core/+/152819 Reviewed-by: Caolán McNamara <caolan.mcnamara@collabora.com> Tested-by: Caolán McNamara <caolan.mcnamara@collabora.com>
