Local html-files cannot be opened and are not shown with ctrl+o
When I try to open local html-help files, e. g. for libreoffice in /usr/share/libreoffice/help they are not opened. I tried with mouse-button right and then selecting Web to open. When I use ctrl+o and navigate to folders containing .html-files, they are not shown in the window to choose files; by contrast, xsl-files are shown (see attached screenshot). The same files presented via a local webserver are opened as they should.
