[LH2417] Text disappears when changing bookmarks

When changing selecting different bookmarks in the bookmark inspector, text in the main area disappears. It reappears after some type of repaint event is fired such as resizing the window. This is similar to the search issue [LH2417],



I am using Windows 10, Scrivener Version: 2.9.0.4 Beta (149671) 64-bit - 30 Mar 2018

Thanks. This is the same underlying bug as 2417.
