Bug #88742 was fixed at https://cgit.freedesktop.org/libreoffice/core/commit/?id=772686adb99137733db79b7d1ab6ebb21bf93b4a Now we need to update the helpcontent to reflect this change: https://opengrok.libreoffice.org/search?project=help&q=%22Styles+and+Formatting%22&defs=&refs=&path=&hist=&type= Also it's no longer a window but a sidebar, so that needs to be changed as well.
Olivier Hallot committed a patch related to this issue. It has been pushed to "master": http://cgit.freedesktop.org/libreoffice/help/commit/?id=c9fc9a65717e174477d11ae4b5d13dfae17848a3 tdf#111651 'Styles and Formatting' -> 'Styles'
