The Menus, Toolbars, and Context Menus tabs have a "Description" box, which is empty no matter what command is selected. When hovering over the box, a tooltip claims "Local help is not installed", but this is not true. I have libreoffice-help-common and libreoffice-help-en-us installed.
Tested on LO PPA v184.108.40.206, and also AppImage (w/ help) v220.127.116.11. First noticed on v6.3.5 if not earlier. All on Ubuntu 19.10.
Steps to Reproduce:
User Profile Reset: No
Issue when the help system was reworked, if the local copy of Help is installed. Otherwise for bug 129720 the command labeling is used to construct a description.
