This other question shows the problem adding horizontal lines (the menu item is simply missing in this version). Strange that no one seems to be addressing the missing menu item. Existing answers (as of writing this) are not helpful, to say the least. I am in no way interested in adding a picture of a line or something strange like that. This is a specific, HTML-supported element that worked fine in the last version with ODT documents.
But even if you copy a horizontal line from somewhere else, or have one in an old document, they won’t actually display correctly. You only get a blank area with the (correct) “Horizontal Line” style listed. This is a horrible functionality regression and is very disappointing.
Is there any way to fix this without reverting to the previous version?
I’ve been a long-time supporter of LibreOffice and this is the first major issue I’ve had. It seems very odd this was allowed through to a full release version. According to this thread, it looks like the art and menu item was simply deleted by a single contributor. That doesn’t sound right. Worst is the part where they decide it isn’t a bug and won’t be fixed.
I would love some help with this strange, strange issue. Thanks in advance for your help.
