Use the wplayNormal layout and autozoom = wpAutoZoomFullPage. Then start a new document with a one line headline and hit enter twice. Then insert a table. Continue writing below the table so that the text starts to fill most of the page. Then the headline disappears, and if you try to edit the headline, what you write is invisible. If you change the zoom or the layoutmode, the (modified) headline reappears.
Julian, can you reproduce this?
