sw: fix not needed invalidation of title field on each keypressco-6.4-39
Type a character, SwDocShell::DoFlushDocInfo() is called because the number of characters changed, and that rapaints all title fields. This happens as SwFormatField::UpdateTextNode() calls SwTextField::ExpandTextField() with bForceNotify=true, because that was needed for conditional text in commit cd94a84b89c476760ad74bf088a5d6f8ba4ce209 (125044: - use field's content cache on <SwTxtFld> construction only, 2014-06-13). Fix the problem by not forcing notifications for title fields in SwFormatField::UpdateTextNode(): SwTextField::ExpandTextField() will send a notification if the expend result differs without forcing as well. (cherry picked from commit 0a32630d11ebdb8b8218faa066c72582ef2f300d) Conflicts: sw/qa/core/txtnode/txtnode.cxx sw/source/core/txtnode/atrfld.cxx Change-Id: I5e46ab6aef33ff5e348d40b8644bcc9cf353c326 Reviewed-on: https://gerrit.libreoffice.org/c/core/+/115783 Tested-by: Jenkins CollaboraOffice <jenkinscollaboraoffice@gmail.com> Reviewed-by: Mike Kaganski <mike.kaganski@collabora.com>
