When cursor is in read-only area, all paragraph/character edit buttons/menu items get disabled, except Increase/Decrease Paragraph Spacing.
To reproduce, create a new writer document, add a section that is protected (or alternatively, insert a table and protect its cells), and put cursor to the protected area. The "Increase/Decrease Paragraph Spacing" items on Formatting toolbar, on Properties sidebar, and in Format->Spacing menu are not disabled. Using them makes relevant changes, which is wrong.
